Year 1 – Semester 1 – Block 1 – Foundations of Medicine – Cell Biology and Biochemistry

informative and interesting way of conveying the subject which helps understanding them much easier.

Me encantó como lo ha explicado, paso a paso, de manera detallada y concisa. He aprendido mucho gracias a este video, ¡gracias!

Dr. Georgina turns difficult topics in genetics into clear and simple concepts that are easy to digest! For the first time I feel like am starting to understand the Central Dogma and related subjects better thanks to her. She's also greatly commited to student success by answering to students questions and concerns about the subject.

To the point. Good organized pathway explanations. Pedagogical presentation skills.

Easy to understand.I like how she uses examples to illustrate passive vs. active transport.

Amazing lecture, Dr. Georgina lessons are by far the best I've had in citology. Very clear and straight forward, perfect for the Mcat. Thank you!

The most important part of this lecture in my opinion is the analogies that Dr. Georgina offers. It really help us to understand for example when she associated the Golgi Complex with a Fedex facility, or when she connects the fact that liver cells have more SER since one of its important functions is detoxification.

I like how she breaks down the information in small and easy to understand pieces. There's no need to overcomplicate things like other science teachers love to do.

So clear and to the point - perfect - love this video

This lesson is explained very well! It's clear to me what Lineweaver-Burk plot means and how enzymes are most efficient when they have high Kcat/low Km

Very well explain and the quizes are a great help

I like all videos & I want to more teach you about this and your lectures is so brilliant

Dr. Ahern is amazing at linking what he's about to teach to previous videos.

So far so good. The videos are easy to follow and I love the questions that pull up at the end of the videos to recall the information. Looking forward on finishing the rest of the modules in biochemistry, including all the other sections.

The video by Lecturio provides an excellent overview of the electron transport chain and chemiosmosis, two of the most important metabolic processes in the cell. These processes work together to produce ATP, the cell's energy currency. One of the most interesting things about the electron transport chain is that it is a highly efficient way to convert energy from food into ATP. The chain uses the energy from NADH and FADH2, two electron carriers that are produced during glycolysis and the Krebs cycle, to pump protons across the inner mitochondrial membrane. This creates a proton gradient, which is like a dam holding back a reservoir of energy. The ATP synthase enzyme then uses the energy of the proton gradient to drive the synthesis of ATP from ADP and inorganic phosphate. This process is called chemiosmosis. The video does a great job of explaining the complex steps of the electron transport chain and chemiosmosis in a clear and concise way. It also provides helpful animations and diagrams that illustrate the process.

I've reviewed the Video, and while it provides a comprehensive overview, there are a few points that need clarification. "Fatty acid synthesis doesn't occur in the mitochondrion; it occurs in the cytoplasm, sequestered from fatty acid oxidation, simplifying the regulation of the two pathways." Clarification: Fatty acid synthesis indeed occurs in the cytoplasm, separate from fatty acid oxidation that takes place in mitochondria. This separation allows for streamlined regulation, ensuring the balance between synthesis and breakdown. "Fatty acid synthesis is chemically similar to the reverse of oxidation, involving joining, reduction, loss of water, and a final reduction, making it essentially the reverse of oxidation." Clarification: Fatty acid synthesis does indeed involve joining of acetyl and malonyl units, reduction steps, and removal of water, making it similar but not exactly the reverse of oxidation. The subtle differences in the chemical steps are crucial for the controlled synthesis of fatty acids. "The enzyme acetyl-CoA carboxylase is regulated through phosphorylation by AMP-activated protein kinase and allosteric binding of citrate, ensuring the balance between synthesis and cellular energy levels." Clarification: Acetyl-CoA carboxylase, a key enzyme in fatty acid synthesis, is indeed regulated through phosphorylation and allosteric binding of citrate. This regulation allows cells to respond to energy demands, modulating fatty acid production accordingly. "Fatty acid synthesis involves a series of steps catalyzed by the multifunctional enzyme fatty acid synthase, where individual activities within the enzyme complex work together, ensuring efficient fatty acid production." Clarification: Fatty acid synthase, a multi functional enzyme complex, plays a central role in fatty acid synthesis. Its individual activities work in harmony within the complex, allowing for the sequential addition of carbon units and the creation of fatty acids up to 16 carbons in length.

The following are the errors in the information you provided: 00:24 The general formula for monosaccharides is Cx(H2O)x, where x is equal to the number of carbon atoms in the monosaccharide. For example, the structural formula for glucose is C6H12O6, which means that it has six carbon atoms and six water molecules. 01:15 The structural formula for lactose is C12H22O11. This means that it is a disaccharide made up of two monosaccharides, glucose and galactose. 01:39 Polysaccharides are polymers of monosaccharides, but they do not necessarily have to have the same repeating sugar unit throughout. For example, amylopectin is a polysaccharide made up of glucose molecules, but it has a branched structure. Here is a corrected version of the information you provided: Carbohydrates are molecules whose name literally means hydrates of carbon. This is because monosaccharides, the simplest carbohydrates, have a ratio of one carbon atom to two hydrogen atoms to one oxygen atom, the same as water. The general formula for monosaccharides is Cx(H2O)x, where x is equal to the number of carbon atoms in the monosaccharide. For example, the structural formula for glucose is C6H12O6, which means that it has six carbon atoms and six water molecules. Disaccharides are carbohydrates that are made up of two monosaccharides. They are formed by a glycosidic linkage between the two monosaccharides. Disaccharides have the general formula C12H22O11. Examples of disaccharides include sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (glucose + glucose). Polysaccharides are carbohydrates that are made up of many monosaccharides. They are formed by glycosidic linkages between the monosaccharides. Polysaccharides have the general formula (C6H10O5)n, where n is the number of monosaccharides in the polysaccharide. Examples of polysaccharides include cellulose, starch, glycogen, and chitin. Polysaccharides do not necessarily have to have the same repeating sugar unit throughout. For example, amylopectin is a polysaccharide made up of glucose molecules, but it has a branched structure.

she is doing very well in explaining the topics and precise.

The lectures are not bad, they have the material, tbey are very well spoken and easy to undersgand. I find some quizz questions to not be relevant, i believe i won't be aske dthese questions on exam. And sometime the material itself feels dry. I am more of a doers, so by solving more complicated questions with the help of a professor would my learning experience much better. But over all not a bad course.

Great Lecturer..well explained. Every section of lectures are meticulously explained. Clearly understood.

Simple, not over-complicated and understandable, all great signs of an amazing lecture.

it's very easy and simply explained and I loved it It was very helpful

Great material easy to learn good pictures …..thank you so much

I am appreciative that Dr. Ahern took the time to update his lectures. Shows he cares. Thank you!

Simply explained. Can't emphasize more how important this is

I like the immediate quiz and 'notes' format after each video.

The information is presented in a way that is easy to understand! Thank you ????

The analogy of the central dogma is the best explanation I've ever heard!!

A great summary and introduction to an important but sometimes confusing topic. The questions following the mini lectures sometimes seemed out of sink, covered in a later lecture, etc. For students using this as a key resource, it is essential they understand that using the suggested textbooks and answering all the questions is necessary if preparing of licensing exams, etc.

Clear and understandable concept with actual molecules shown aswell which is very helpful.

Bio means life, chemistry means the composition of matter and energy requirements for life to exist. Chemicals and anyone

I appreciate the approach to clear concepts and road map to the subject matter.

This subject was amazing to learn, and Georgina makes it easy to understand, so I could say that really loved this course, thank you.

Well structured and comprehensible. Ms Georgina Cornwall makes pleasant pauses between sentences, speaks clearly and explains so that it is easy to follow. The questions afterwards are also very helpful.

Prof Kevin Ahern is incredible! Great summary and really well explained!

I am enjoying the lectures. I have two, very minor issues. 1. They are a bit too "granular". Some are so short as to prevent you from digesting the material as it is presented. 2. On several occasions, the questions were not covered in that segment but rather in the next!

It was just what I really needed I love lecturio so much

Topic is not comparing the topics from previous topics in the table form. Then students will remembered

not explned wel as the topic is difficult and you made it a lot much boring

easy and complete explanation for a complex topic, you're the best!

As a retired physician, still professing clinical subjects at a medical school, it is great to have an opportunity to revisit topics last studied in depth in the 1970s! It is presented in clear and digestible aliquots and in a logical sequence by qualified lecturers.

The teaching is basic and does not represent material tested on USMLE exams. The concepts are taught by an instructor unfamiliar with the actual exam. Technically, questions pop up in the middle of a sentence and sometimes before the subject matter tested was mentioned.

An excellent and detailed description of each phase with emphases on correct language.

All the lectures have been so, so helpful. Thank you so much!

Ms Cornwall presentations hard to understand with no clear imaging and orientation of the slides

Concise and easy to understand content. Thank you Dr.Georgina!

Great review for practicing physicians who have been out of med school for some time.

Kevin is Amazing man, his body language get a lot to his explanation!

It is too simple like introductory biology. We need more advanced molecular biology

lack of information no explanation ,its like you are reading headings. and the quiz questions are poorly made.

excellent explanation of topic very difficult to understand for a med student

I really liked and very helpful lectures thank u sir for your explanation

Great way to remember the three portions of the ribosome!

I, really, liked ALL of Dr. Cornwall's lectures, but did NOT find time to rate them! I am, still, trying to put it all together because molecular biology is my most difficult subject, but Dr. Cornwall put together much that I knew -- and I am far better off than beforehand! I, definitely, now understand as much as any medical student ought to about molecular biology -- and thus, I am glad that I made notes the whole way, giving me paperwork to re-think all that Dr. Cornwall taught me! Thus, I wish Dr. Cornwall the best and am grateful! :)

Breaks concepts down easily and love the review questions. Helps solidify learning.

Thank you, Dt. Cornwall, for this chapter!!! It was very useful and finally, with the help of your tips, mnemonic and your awesome teaching style, I could understand the process!

I have really learned. Before, I was wondering why study, or cram all those pathways and enzymes. How Professor Kevin Ahern explains and bring out concepts, Oh my God so great. He was born a teacher and just polished by learning! He never leaves behind any one, even the slow learners can pick, because once one understands the basic, the necessary complex facts can be understood quite faster! I am now thinking of mastering in Biochemistry, besides my goal of Internal medicine. To be the best Physician, Biochemistry I have understood is one of the vital tools! In my Nursing practice, we lost a 10 yr old male with Liver Cirrhosis from a liver disease, which was diagnosed in early age. Now, I am thinking of a Deficiency of the Transaldolase enzyme!! Ahh save for my little knowledge! Kind regards!

Really a great and elaborate presentation. Thanks Prof. Kevin. Now I no longer struggle in cramming Biochemistry but rather find the subject interesting. I wish I started using your lecture guide early in Medical school, but any way not yet late! Thank you once again.

very new insight to explain macronutrient and fruit for thought

Very dense lecture. Maybe a bit too in-depth in some places, but excellent discussion about the importance of carbohydrates and the key enzymes and reactions that underly the process.

Excellent review and explanations of the different vitamins and their various forms and functions.

Really liked Enough chemistry to explain it / not more Shows that she is passonate about the subject

Georgia Cornwall has done a conscientious job at teaching molecular and cellular biology -- and I enjoy it daily! :)

Awesome lectures by Sir. he explain every step and every single reaction with detail thank u.

It was informative in a simple way and the question after make you make sure you got it

There are mistakes in the video and they make the material more confusing than it should be.

A very concise content with relevant short videos and quizzes. Great program

I can easily follow the sequence of information. The important details are also emphasized, making it easier for recall.

Nice delivery but as much as Dr tries to break it down,it looks a bit abstract. Perhaps some mneumonic would help

I really like the explanations and detailed structures used. The structures make it easier to understand.

Very clear and easy to understand. I enjoyed the visuals.

The explanation are cleared. However, they are not included many scientific terms and scientific details that necessary to well understand the content and to do well in the MCAT exam. In other words the content of that lecture are too simple for MCAT students.

I understood very well the topics. I learned things I didn't before in school

very precise, for a person with basic knowledge it is very helpful although I think it could be a bit difficult to understand for someone who does not know anything about these issues.

Professor Kevin make it enjoyable course; It helped not only in remembering many info that I forgot in the class, but also I did learn many new valuable information. The fact that the explanation provided by Dr. Kevin is so easy to understand and memorize, make this course very interesting.

The explanation about the carbs are very clear and detail. Which make easier for any student and professor to better understand the carbs, their pathway, and the enzymes that work in those pathways.

I am a biochemistry student, the videos on lecturio have been so amazing. The lectures are superb. The language is easily understood and in a very friendly way. The concepts are been discussed fully and appropriately. It has made me to understand biochemistry more.

I love cell biology and this classes are amazing. Thank you

ok ok ok ok ok ok ok ok ok ok ok ok

Thank you so much It was great I enjoyed watching these videos

just got the structure formation of a f actin support epithelial

How can the process of charging of tRNA be explained if the concept of tRNA has not been presented? What tRNA does and then how it's charged. I am loosing too much time googling stuff. Maybe it has been presented, but it's not part of this playlist, which should be complete.

This course is easy to understand and memorize. I am 100% recommending this course to anyone in need of learning sciences.

Very good teaching. Very good images and very good explanation.

This explanation was not clear at all. I had to research a lot of information elsewhere to understand the concepts presented. This is the exact opposite of what is to be expected of something that should make students life easier.

I like how Dr. Kevin discussed all the topics, simple and easy to understand.

ten words ten words ten words ten words ten words ten words ten words ten words ten words

Why does it require ten words and stuff, can't I just rate the lecture and get over with it?

Course is not only informative, but very enjoyable to listen. Also, I love your dressing style.

Very concise and simple explanations. He made it easy to understand.

yummye yummy yumme yom? yommer yom yom yom; yom yom yom.

Simplified and we'll explained. The teacher knows her topics well and explains in a simple way for all to understand.

The lecture breaks it down so simple that it’s easier to understand. There’s still more factors that I’m sure they’ll be discussed in other lectures but it’s perfect to help to create a strong foundation in your knowledge

He speaks very well. Concepts delivered very well. I could understand most of his theory

Concepts are very good and explanation is amazing. I'm in love with it

Great Visualization and the elaborative method of teaching is right according to my mind.

Amino acid MetabolismThe lectures are very thorough and give good details about what is high yield.

Dr. Ahem explained a complex concept in a very interesting and simple way. Straight to the point and informative. Thank you

Great to be with you on this platform as student studying medicine hopefully need to be lovely doctor

very good knowledge gained. Learnt a lot about RNA and DNA and messenger RNA

very clear , and natural. High yield, very in depth. Great knowledge gained

brief , clear, high yield, relaxed, in depth lectures. With a question and answer section at the end of every lecture. I'm loving it

One of the best teachers in Lecturio my personal favourite class

FINALLY! I get replicated homologous chromosomes! Professor Cornwall cleared up a haze I had about this point for years in 3 seconds. I don't understand why there are not more people who emphasis the difference between homologous and replicated homologous chromosomes. Thank you Professor Cornwall.

I haven’t seen such an amazing teacher in my life My most favourite teacher

The concepts mentioned in this lecture are very confusing and poorly explained. She made no effort to clarify the meaning of homeodomain, homeoprotein, and other such concepts. Also, she seems very unsure of what she is teaching and the speed is too fast to properly retain the information.

very bad organization of the material vitamin d , then calcium, then vitamin d, then calcium. and there are lots of overlap between classes

Dr Kevin explains the concepts slowly and with emphasis. He also includes the physiological aspects, making biochemistry sound more biological rather than chemical

I loved this lecture ´cause dr ahern was so clear and it really helped me understand this topic.

Awesome review , covering all the important concepts with clear explanation

The professor teaches very well, and difficult concepts are taught in a clear, concise manner.

Basics of this course can be explained in a very detailed manner

It was very comprehensive and I loved how easy it was to understand

All of the videos on this topic are very good, thank you!! It made me finally understand it. I wish we would have more details on the pathologies related to the Purine and Pyrimidine pathways.

It was awesome factual and easy to understand.Amoino acid Metabolism clear relationship to general human Anatomy.

The lecture was simple understandable and Clear , it gives a broad explanation about the fundamentals of biochemistry

Amazing Dr. Kevin! Thank you very much for this course!

Excellent lecturer. Manages to efficiently explain concepts in a very concise and informative way leaving very little room for confusion. He's obvioulsy a master in this field and I'd definitely recommend his lectures to anyone.

Short and simple. Right through to the significant things. Thanks to the professor.

I appreciate these refresher and very well-explained building lectures.

Made something so complex easy. I've always had trouble here.

The content of the lecture/presentation is excellent. Has somebody else prepared the material?

Yes, hormones and their transduction signals are important like a cardiac conduction system starting form the Sino-atrial node (SA) finishing in the Purkinjie fibres . I mean Hormones and signal transduction are really well explained by a doctor doctor Kevin Ahern . He has been presenting the most complicated part of the medicine course so well. In terms of pregnant patient for example who does need an extra attention and management as they go though various hormonal changes while caring out pregnancy and delivery tasks. I cant thank enough for his contribution . I much appreciated.

Only wish the section would have also included videos or as link to videos posted elsewhere to Vitamin C, B1,B2,B6 and the rest of the water soluble Vittamins.

It is Clearly clearly Clearly clearly Clearly clearly Clearly clearly

I loved this lecture! Everything was so well explained: simple, straightforward, and I especially love few external tidbits thrown in such as the meteorite portion. It helps to remember these facts. Thank you!

This lecture was one of my favorites as it made something so confusing perfectly digestible.

Dr. Ahern is a very good lecturer. He explains concepts very clearly.

This lecture provided me with so much clarity. Thank you

aa a aa aa aaava aaav aaa aaa a s s s

Excellent resource. Thank you. I also enjoy the quizzes and practice medical scenarios.

in depth knowledge on DNA splicing, ecor 1 and so the base pairs want to stick together and then ligase comes along to stick together the backbones, the phosphate-sugar backbones. Here you can see how the two pieces come together and now we have a recombinant DNA molecule. Again, we are generally looking at a circular chromosome and a foreign piece of DNA being inserted into that circular chromosome and so we'll see two ends of sticky ends and insertion of that sequence.

This lecture gave me a brief knowledge on how rDNA is made.

Easy to understand I like that subject Clear explanations relevant for my dream job

He explains on a perfect and short way making it easier to understand

Wonderful, simple and easy-to-understand video. Finally got it

This video has several problems. It does not seem to be a continuation of the previous ones, it has unclear information, the reparation itself is not explained, and the name dropping doesn't help either.

I liked the lecture. It was clear and concise. I liked it better if the lecturer used more visuals of techniques.

Very informative and detailed. It allows you to understand the concepts on a fundamental level.

The best explanation, Concise and to the point. Thank you so much.

Excellent review of the basics; been a practicing Doctor of Chiropractic for 27 years and your videos are bringing it all back again! On the way to taking the MCAT to get my medical doctorate in Pediatric Neurology specializing in neurosurgery. Planning on beginning practice when I am around 68/69...my second career. Thank you for helping me do this great endeavor!!

Love this lecture. Dr. Ahern explains much better than my professor.

I FULLY recommend!! Definitely has help out in my courses.

I liked this lecture and I also like this teacher. I just sometimes find the explanations a little be confusing.

A student could do this lecture and it would be easier to understand. we expect better lectures from professors.

Five-star score not only for the high-yield information but also for the excellent teachers, spaced repetition tests and articles. Thank you all for bringing this amazing learning format!!

best explanation of the iron transport on the web that I have come across. Good clear diagrams.

They give clear explanations on all topics in such a way that it is easier to grasp. I personally enjoy learning more about a particular topic and Lecturio is the perfect platform to do that as well. I highly recommend Lecturio to all students for better understanding of relevant topics.

Really good explanation. And I like the professor. I understood

Thank you so much This video helped me so much en my sesions of study

Very good lecture! Interesting clinical correlation (celiac disease). Thank you!

I'm really enjoying Dr. Cornwall lectures, I love the way she explains things!

Clearly presented talks and material. Very useful for undergraduate students.

Please is important to add more clinical correlation, clinical cases and bridge to other areas: pharmacology, microbiology, etc. Usmle test the integration of knowledge.

Comprehensive, latest information presented in an easy to understand formats. Thanks!

Interesting. I have tries to learn this about 2-3 times but never quiet stuck in my mind. Too easy to forget why an enzyme does this or that, however Dr.Kevins way of sharing the WHY this is significant really helped conndct the dots.

Interesting. Mental thirst quenchinly good. Interconnected. Just enough info. Dr.kevin fun lectures.

I really appreciate how Professor Ahern broke down this topic (no pun intended). He does a really good job at tying things from other lectures together really bringing these pathways together while also trying to enrich our understanding of the context behind em. Thank you for your hard work!

I honestly had a lot of fun listening to Professor Ahern. You can tell he is really passionate about Biochem. I learned a lot. Great course if you're interested in understanding aspects of the metabolic pathways conceptually while appreciating the details/context that enrich your understanding of them and how they are interrelated.

ok. could use improvement please include that Kinesin and Dynein are ATPases that use energy. also that only Kinesin is displayed here. I was so busy looking for Dynein information, that Kinesin info went out the other ear. This could be better by improving the diagram.

I liked the way the R and T states where explained. It all became very clear

This course is an excellent presentation of biochemistry. Professor Ahern presents the material in a clear, concise, easy to understand format that is easy to follow. I really like that I can pick and choose the lectures I need to watch, particularly those that I need to prepare for my upcoming exam. I find the review questions very helpful. Overall, I am finding the course very helpful and I am looking forward to completing more of it.

I like that Dr. Ahern's way of presenting the topics is informative and does not make me sleep. Usually, our classes make us feel drowsy because of too much information. It helped me understand the concepts more and I was less distracted.

It was easy to understand, and some details, which i think was enough! not too much information, but enough

Thank you Dr. Ahern for this very comprehensive lecture. Going through the biochem book makes this topic very complicated. It is amazing how you can simplify this topic to get to the point and what we actually need to understand.

Difficult to memorize all pathways I think it could be more interesting

Like the step-by-step discussion. Make it easier for me.

Covered a vast portion of the basics that are the most important part of the foundation. The structure of the course is phenomenal and the way it is carried out is engaging and made extremely interesting. Concepts are crystal clear after going through the whole course. Thank you so much, psyched to have found this! I only wish this material was downloadable for future reference. Hoping it could be. Thanks again! This has cleared the slightest doubts Ive ever had, hoping to have many more courses conducted by Georgina Cornwall.

not very engaging with the viewer, and it could be even more dynamic

I love it! It's clear and concise! Dr.Ahern is a gem to learn from. He breaks it down to where I can understand.

Nice speaker and illustrations. The lectures were engaging. Thank you!

This topic is OVERLY simplified. It needs more in-depth explaination, which she claimed to offer later. But this brief section creates even more confusion... Maybe it is better to do a PROPER introduction, or just cut this one out... Also, she herself seems to be unsure and confused. I am not sure what her profession is, but DNA doesn't seem to be a topic, which she should lecture on... In the middle of the video she just blanked, and kind of skipped on some points... (That's not the first time or first lecture that she does that...) P.S. The powerpoint is also not accurate... The coding strand around 0:52 is indicated as template strand... This lecture is quite disappointing, and frankly, a very low quality compare to other Lecturio's lectures.

Really good divided and explanation, with good examples and great review questions

Comprehensive course with exemplary format & teaching style to explain core concepts.

Aminoacid metabolism Is not easy to understand but still good !!

fast confusing order of explaining Its not like it simlifies anything the way its explained is quite fast and confusing very mono tone

Kevin Ahern is a really good teacher, I really enjoy his lectures, but sometimes it's hard to follow the lecture due to the presentation picturing one thing and him talking about something else. And also when he's talking about about the presentation I wished he had some sort of pointer so I would be easier to know what structure he's talking about????????

More organization is needed to explain this lecture because is an important part of the DNA synthesis.

I love her course. She explains in a very understandable way.

Professor gives a very clear explanation, easily understand. Thank you.

Beautiful and very good explanation . easy slides. thankyou. study matter also provided

Content is spot on. And quizzes at the end of each videos are very helpful. Hope Georgina used a cursor or infra red light to point exactly what she was talking similar to other lecturers from other videos. An animated video clip of how each or some of the topics would be very useful.

Hello, I love supporting women in science and education, etc. I also will share my honest opinion to improve the educational site. This lecturer, while alright, is not the best you could get for Lecturio students. Her constant glancing over her notes is distracting and she is not very well articulated. Even though she is Ph.D., she has not digested her lecturing materials to the master's level. It is very unfortunate that she lectures on one of the most important subjects within your platform. Why you chose her? For the sake of diversity and involvement? I am sure there are much better and knowledgeable lady lecturers. Did not you see the disengagement and flaw after a couple of her lectures? Was she so cheap?

The presentation is very nice and helpfuly The organization of topics was very good

I am no longer scared of metabolic pathways. thank you so much.

I'm impressed with how high yield the information is. The professor touches very important aspects in just the shortest time that one video has, and that is really impressive. I do have a degree in Biochemistry and molecular biology and so this is really making me master the course gradually. For sure I'm recommending this course to my friends from same college already who aspire studying medicine like me.

I liked to much because maintain the point of what are she explaining the theme with clarity and didactic form about the macromolecules of life the first principle to begin the content of the nature of the Body , systems organs ,tissues and cells.

Incredible Easy to follow the class The professor had my attention all the class

It was hard to understand It could be better another way to explain the topic

Biochemistry by Georgina Cornwall is not good at all, she reads all the time and she doesn't even know what to talk about.

She didn't talk about the template strand. the prof fumbled with the coding strand and im actually confused if the coding strand, or the tremplate strand matches the sequence of the mRNA. She definitely seems disorganized. It didn't flow at all.

The videos are shorts and specific an also great explanations

I liked these explanations, but if you are a college student this may not be for you

Really course is wonderful, and very useful and Professor has easy and simplified explanation of most of the complex topics in biochemistry.

Great explanation with great examples . Knowledgeable in subject matter , content up to date

THE TRANSLATION IS NOT CORRECT, THERE IS NO CONSISTENCY IN THE SENTENCES

Very condensed, but a well-taught lecture. I love the teacher´s style.

Thankyou so much for the opportunity to relearn most of the important and key concepts related to this cornerstone foundation to Medicine & Life Sciences! Wish I had this tool in my undergrad days!!

Nice explanation, very useful, easy to follow. very useful reminder of basics.

SHE IS NOT CONFIDENT IN TEACHING AND RUINS THE MOOD OF LEARNING

It was a great lecture, I learn a lot. Thank you Prof. Ahern.

He is the best here , I swear Idk but I like him

Its excellent because there is more physical and clinical correlation and enzyme mechanism simplified

Great course for introductory level biochemistry. Prof. Kevin Ahen is a great teacher, knowing not only the topic but it's historical background...

I noticed that there weren't any lectures on mineral metabolism in the library. I think students would really appreciate it if you made a module on this topic as it has a lot of biomedical importance and some relevant diseases are associated with it.

He's a legend ooh I don't know what else should I say to complete 10 words

biochemistry was tough as I havent chemistry before. Had to keep reviewing, loved the tests and course presentation and so satisfying when i got the answers right. Great system for people like me . cant wait to do other subjects when i finish this one.

such a hard concept explained so easy and well. such an amazing work sir

La verdad es que es muy buen curso, el ponente explica demasiado bien y me gusto mucho qué hay actualizaciones

what an amazing lecture god bless u sir and i wish to meet u someday

Each and every concept is explained with each lecture it has helped me in getting to know things well rather than just learning.

Thank you so much; Nonetheless, i really need to let you know your vocabulary is above my reach

I could not understand it good at that in my university college friends

Great explanation about the Bohr effect, thank you very much doctor

I understand very well, thank you Professor Kevin, these help me a lot

Dr. Ahern pointed out very interesting aspects like heat generation/high energy of PEP and the 2,3-BPG production. Maybe I wasn't paying attention the first time I learned about glycolysis, but this extra integrative information it makes this step easier to remember. Actually, in generally, these human focused biochemistry lectures, are easier to digest, since when I learned it originally, it was mixed with plant and microbial biochem.

one of the best teacher ..yo mam ............really enjoyed it

It was much needed review for me in general. Thank you.

Enjoyed these videos very much. They helped me understand concepts I was struggling with.

Great work here,,, I’m so happy for the clearly understandable English

i liked the details and visualization. should have been there more mobility in the slides tho.

The lectures on Enzyme and Enzymes Kinetics were thorough. There were detailed information on some important concepts.

Need to explain better as it is very complicated and confuses us even more than we were before

Nice course very complete in every sense, I like it, keep like that.

Awesome overview! Thank you! Particularly liked the gluten example. Also graphics were good - will stick in my brain longer.

Lesson was so fast and not understandable .Lecturer should have gone from easy points to harder points.She could not make it easier this topic for me .She did not use her hand at all during the lesson.This is so lazy way for giving a lesson and unproffesional.

I dont know if its the diagram or what the doctor is saying but i just cant understand the MAP kinase and the GEF and everything else afterwards

I just find the need for an extra time revising this, particularly offline. I always find my self making some notes unlike Anatomy!

Prof Ahern explains very well & makes the key steps/enzymes memorable (eg PEP is full of pep!)

So good explications with a nice and simple way . I really appreciate your effort .

Explica las cosas super simples y puntuales, se memoriza rapido de esa manera

she reads from her notes too much, strikes me as someone who does not have a firm grasp on what she is teaching.

I think it’s too fast, and not with details so please correct these problems

Magnificent lecture about polysaccharides and their functions for storage and release

Very clear and succinct. May have gone a bit too fast, but that's always manageable

The video highlights the important concepts about the hydrophobic amino acids group

I recommend include the cc out of slides screen, the letters do not allow to watch the information

The lectures are very thorough and give good details about what is high yield.

I love the way he explained enzyme.... A brief and easy to understand lecture

adioasd oiaj doias ds dioas jdoias jdoas djoi asdjoia sd o

Basic topics which i had difficulties in understanding has been well explained and now I have fixed the knowledge :) Suggestion: it's hard to cover the extremely fast growing biotechnology topic but I guess "omics" would be good to add

Thank you Dr. Kevin Ahern. You made me fall in love with biochemistry.

I really liked the explanation, finally after 2 years, I understand this!! Thanks :)

I always enjoyed Dr Ahern's handling of the Biochemistry subject, especially his eplanations

I really liked it and enjoyed Dr Cornwall'ss explanation. The only issue was that the video slowed at some point.

Despite the mishaps, I thought the information was understandable. Especially the ending when she connected Trp and Lac operons with repressible and inducible.

It's is just good that's why 4. I dislike that it's doesn't explain clinical too much

It's okay.... But somehow hard to comprehend. I will love if you can make the teaching much easier to grasp.

Every slide has been clearly explained in detailed form. Thanks sir.

It's unfathomable how much this lecture has saved my time. Though I would appreciate a quick-summary of the products turning into intermediates for other cycles. Like with how g-1-p turns into g-6-p

I saw many times the video, take notes but I don't understand at all this video; think is some confusing :(

The lecture simplified glycogenesis to extreme simplicity. It truly helped save around 30 minutes from my lecture, by providing adequate information

Hi I appretiate her lectures about biochemistry, l hope the following lectures would offer me more interesting information.

lecturer is breathing heavily that is kind of distracting. I don't know if it is because she is wearing the mic very close. lessons were nice tho.

this is amazing thank you , i gained a lot of info about viruses that i have not know before

I am in my first semester of Bachelor of Science in Biomedicine in Switzerland and the courses are helping me a lot. I can watch your videos after a whole day of studying and I am always having fun! I get a great overview and know what the most important concepts are. I also have no issues remembering what I learn here. Thanks a lot! I learn new things while answering the quiz questions as well, they are smartly structured and help a lot as well.

very clear explanations and the questions helped me understand the content

Love your lectures, Professor. It is helping me a lot reviewing Biology as It's been years since my basic science years.

this is a good lecture i really understand a lot of thing i haven't know before tysm

Although the whole course (and actually the whole of Lecturio) is absolutely wonderful, I enjoyed this lecture with Dr. Cornwall so thoroughly, that it felt like time was passing by rapidly! Before I knew it, the lecture was over and I had learned so much! Dr. Cornwall has a way of explaining things that makes you understand is the matter longterm and makes you curious to look deeper into it. Thank you very much for everything! Eileen Dara Greetings from Belgium

simply explained so well understood, very well done. lots of info but concise

I select leturio because its teaching method is very awesome knowledge base Usmle type based

It's good, informative not as detailed as I need it to be but it's a good framework to build on

Great concise videos covering salient points in biotech. Most of material is well presented though some concepts I've had to supplement with other sources to fully understand. Overall, great useful series. Thank-you Dr. Cornwall!

It is a good introduction for the following classes. It's not confusing, but more information could be added

Liked it too much as it's so easy to understand ????...but cannot afford premium ????

this video is short and easy to understand. Thanks Teacher

Good explanation. Pretty bad diagram. Animation probably would work better.

First of all, I like the depth of this lecture and Professor Ahern is clearly very knowledgeable and concise on the the topic being discussed. And I also like due to the fact that this video is clearly a high-yield resource which is very helpful for my upcoming medical exam. However, I believe that this could have been better had the previous cycles preceding the formation of OMP explained as well in order for us the students to be able to get the essence of the information better. That's all I have got to say

Dr. Cornwall is awesome! Her lecture are clear and concise. She makes the material so much more digestible.

Dr. Cornwall is fantastic! The biotechnology series helped me SO MUCH going into lecture.

She keeps it short and simple. Great work in this video. It's great prep before going into a lecture!

Me encantan las clases son muy explicativas y muy detalladas , simplemente excelente!!!

Excellent Lecture from lecturio; I highly recommended for students from medical school. It is an excellent learning platform.

i enjoyed every second of this video and it opened my mind to study more and become what i have always wanted to be a radiologist

I love lecturio, it's the best app in the world. Lecturio has everything you want and can help you to be the best in your class and also be the doctor you want. Lecturio is an opportunity that can give you the change of your student life.

Concise and clear; exactly what I needed for this topic, thank you.

Good amount of detail in digestable amounts. Very much appreciate able to run the videos at different speeds.

No explanation at all just reading , sorry for that , No interaction

Very good review .enjoyed the enthusiasm. Visuals were ok but not really understood.!

It's great to learn from someone who's enthuisiastic about their specialty and even better at teaching it. Thank you Dr. Ahern (:

This lecture is amazing and I loved the explanation regarding the conformational change of hexocinase during the reaction.

His explanations are very good. Biochemistry made easy!! He is very good in teaching.

beautifuly explained. thankyou!! Every point in every step was explained nicely.

I like the short videos. They described what’s important and later you get questions about the video.

TOO SIMPLIFIED AND IT SEEMS LIKE THE LECTURER WASN'T WELL-PREPARED FOR THE LECTURE KEEP SAYING NONSENSICAL WORDS. I AM REALLY FURIOUS AND FRUSTRATED LISTENING TO HER LECTURE.

Me agrada como explica las cosas la Dra, creo que lo hace que sea entendible de forma sencilla para cualquiera

La Dra explica muy bien y de manera sencilla, algo que me gustó mucho son las analogías que utiliza para dejar claras las cosas, creo que eso lo facilita

I belive she is very clear and resume complicated topics nicely.

I suppose it depends on your learning style. That is, most of the medical students I've spoken to, appreciate concise and coherent lectures - Unfortunately, in my personal opinion, this micro-lecture lacked the fundamental high concentration of information that most of us are looking for - to take notes, and practice the spaced repetition model. Instead, her speaking pace, and vocal expression are slightly too fast and the way in which she attempts to outline a basic idea isn't linear in nature which leads the viewer wanting to know more, while simultaneously trying to ignore the off-topic rants. Note: Clearly, she's qualified to teach - however, valid of a point that may be, doesn't mean she has the practical communication skills to do so. Therefore, this is not a question of intelligence, rather - communication and linguistic expression. There will certainly people who prefer this method, I however, can not recommend.

I had many doubts but with the lection, I improved much better

The lectures seem to cover all the necessary contents, but it’s often difficult to understand the topic until I go over the video again for several times.

I love having access to such rich learning material, thanks for making this an available resource. My only criticism would be that the quiz questions could use improvement and the professor could talk slower to make note taking easier. Overall, very grateful to have found this!

This lecture clearly points out the differences between prokaryotic and eukaryotic cells in protein synthesis. It would be helpful for those who wish to briefly know how proteins are formed in each type of cell.

It is a good explanation for a complex topic, with only the most important

Teacher speak slowly to help me understand Glucose in my body

rate of speech is good and i understanded the subject he explains it very simple

me gusto muchísimo lo recomiendo a todo el mundo que quiera saber mas

complicated topic but I think I got it, though the Tyrosine kinase itself is a bit complex

I like the format - the lectures are "short and sweet". The lecturer is reasonable easy to listen to. Perhaps it is just because this is a foundation course, but it does feel this material may not be in-depth enough for USMLE step 1. (Or perhaps because it's re-used for non-USMLE students?). The questions are just "okay". There are a few errors, and a couple questions could be worded better. It also seems that some of these questions are testing material that seems only marginally important, and may not be very "high-yield". I wish there was an option to flag review questions to not be included in the "spaced repetition". The "spaced repetition" idea should be for memorizing the most important details, and I don't really want to be memorizing questions that I think are of little importance, incorrect, or poorly worded. (It'd also be a good way your you at Lecturio to decide which questions should be revised - if many people flag it as "don't review again", the question probably needs revision.)

not clear voice . . . . . . . . . . comparatively worse than other videos, others are good.

Understandable!!! Easy to remember! And pretty useful!!! You really need to learn basics topics in Med career it surely make you to be highlighted over another students

It helped me clarify some topics I had been having trouble with.

Sorry, the following videos have the information that I was looking for, sorry again

Amazing way of teaching, compact and efficient. Really good job, keep doing it Mr. Ahern.

Has high yield infos which are not in other lecturer's lectures

As I stated in prior lessons, Dr. Cornwall is such of an amazing instructor!!! She makes easy to understand heavy contents

the instructor is very clear and is easy to follow

Dr. Cornwall did a very great job with this.. The big picture simplified everything and made studying into little details easy.

very didactic I really enjoy Dr. Cornwall lectures, definitely Lecturio was the best addition to my preparation

el contenido esta muy bueno, solo que la traducción tiene falencias y dificulta entender los conceptos adecuadamente.

Everything is confusing. The diagrams and what she was saying didnt allign. ALso she never gave the answer to the number of chromosomes in each stage of meiosis and mitosis

I really like the video, makes medical biochemistry easier to understand

My professors at university failed to explain lipid metabolism in an understandable manner. Prof Ahern does a great job in explaining complex topics and I am really grateful for that. Thank you

the explanation is complicated it could be simplified more better

I loved it, really interesting and easy to comprehend, thank you very much :)

Very well taught, good refresher. The high yield points are in there too.

Very well explained. Would have appreciated had the lecture been a bit more comprehensive on certain topics, like in DNA replication and also a dynamic step by step diagram of the process would have been better to understand.

Need more mcq 's for practice and good content. Very clear concept s

The lectures are great... But I just feel like they are too expansive... Not very suitable for a dedicated study period

Very good Thanks Really it doesn't take much time and its really good

the lecrure is detailed and very comprehensive it is well presented i also liked the quiz that comes afer the lecure.

Excellent breakdown of key topics and very easy to follow.

It almost always fails to explain 'why'. These lists are available in any textbook. I was looking for an explanation to understand it. Also, visually it is looking at a table for 5 minutes, pictures could have explained better.

Before Lecturio I struggled with comprehending the mechanism of proteases and enzyme kinetics. Dr. Ahern brilliantly & easily explained these concepts in less than 5 minutes. I am currently in a graduate program for Medical Sciences, we have cumulative exams every quarter & I was just memorizing the info but now I finally understand. I recommend Lecturio to pre-meds, MCAT, and Med students.

Kevin sir explanation is very very nice and it's an extraordinary talent and explanation but little more information should be presented in power point slides so that we can learn more and more by step by step .. Thank you sir From Sanjeev India

Dear sir/madam In regard to the Biochemistry basics,I am much satisfied by the cours.In fact,the videos concerning biochemitry basics are well summarized and are full of useful information in the regard of médical studies.Because of this,I am enjoying the course and continuing either to learn much more . Yours sincerely Asher Hategekamungu

Dr. Ahern is a fantastic lecturer. All the course is simply awsome.

Dr. Ahern is a fantastic lecturer. All the course is simply awsome.

It is very concise but it provides enough information. I am very satisfied with Lecturio because this course and Biochemistry are exactly what i was looking for.

The video episodes are way too short, need to go back and start over every 3-4 minutes. I think there should be a option to view the topic in one full video. Otherwise the subjects are well covered in an understandable manner. Many thanks

The way of teaching of Georgina is really impresive, i understanded everything. The best classes ever.

The course was easy to follow and has good illustrations of the concepts. I also like the quiz portion of the course.

Very comprehensive lecture . It' s clear and simple. Thank you for your work .

this presentation was good and the way sir explained the concepts was nice

Great Great great great great great great great great great

Great professor and easy biochemistry topics to learn with good explanation.

O really like it , because the lectures are very clear. And I understand everyrhing.

I work in a large public hospital biochemistry routine department, when I studied this subject there where no computers, only text books. So this is a refresher and update of the subject. I am enjoying this 'new' way of learning and it enhances my work knowledge as understanding theory is important for performing work well.

difficult subjects are explained by simple words by Georgina. Thanks so much!

Whenever I get confused about a pathway, I come to watch these videos and it helps tremendously. Thank you for what you do.

I recommend everyone to Follow the 100 Day Study Plan given in Lecturio App. Its Amazing.

VERY clear explanation of how this works, I love Ahern's lectures.

hi first of all she is talking very will as good speaker and the explanation in different lecture was so systematic and will prepared and hit the main points that I'm really interested to her course of biology.

It is an xcellent explication! I understend it at all. Thank you

Great lecture! Very simplified and friendly explained. Thanks so much !

Each RNA should be shown in the picture like above

I like his style and respect his effort. I've been using these lecturers to review my knowledge

It is a good course but the content here is not really high yield.Do we need to spend so much time on it?

Very clear and useful for me to finally get a grip on this topic.

i can't understand why a lot of amazing videos have 1star points

I find the teaching style to be effective and well planned. I use lecturio for supplimenting the topics taught in my classes

Dr. Cornwall makes the topics easy to understand and retain. Her approach is not overwhelming but yet not so simple you are bored.

The lecturer tripping up make it a little difficult to follow but it is made clear in the end.

Talking about things that aren't on the slide https://www.ratemyprofessors.com/ShowRatings.jsp?tid=833581

Very detailed. Moves through information and a good pace. Sifts out the important information versus stuff we don't need to know for the exam.

the concepts are clear and the time is enough, examples are short.

Very insightful and brilliant explanation. I learned very much in this lecture! School professor just skip much of the importance in PPP!

hi Biochemistry's videos are interesting and give me information, the orator pronounce correctly. As you know I do my best to prepare ecfmg exam and board examination next, of course after having sufficiently training and advices under your guidance I would like to apply ecfmg examination this year, now would you please give me more information for preparing step one and step 2 exam.

This is incredibly difficult to follow with the lecturer mis-speaking constantly

??? ???? ?? ??? ?? ??? ??? ???? ??? ?? ?? ??? ?? ??? ???

I believe the term is entropy is misused in this lecture.

Excellent lecture, well explained so I could understand it. So important to understand and not just memorize these topics.

Excellent lecture. Understood Bohr effect better than ever. I love these lectures.

Most of us studying at this point (USMLE Prep) know this stuff well, however; this does provide a good refresher to get the juices flowing in the right direction while studying for the boards.

Misuse of the words fludity and stability as if they were synonyms makes answering the question at the end confusing. Other than that, it's a good lecture.

This videos are amazing, the professor is excellent and his explications are clear

He is a very Good Teacher as he teaches as if he was narrating a story.

Thanks Mr Kevin for your time, dedication and preparation, blessings my man!!! happy 2020

Awesome analogy great lecture! Very nice lectures overall I really enjoyed them. even though I have taught this topics and I know them fairly well. I enjoy little gems of information I received through these lectures, and new understanding

The Professor is excellent, every one can understand easily de concepts

Amazing explanation made me understand the concept clearly in a short time

This is one of the few videos in this video series where the video cuts before the lecturer is done talking or before she's done with the material for the section. For example, in this one she only discusses E site and video cuts... what about the other 2 sites on the ribosome?

It was so enjoy to understand the biochemistry and the teacher was so great.

The instructor reading off the podium is not appreciated. It doesn't entice the viewer to keep watching.

I like a lot both the explanations and illustrations to the topic.

Excellent teacher . Great lectures . He knows how to teach the subject matter

I like how Dr. Cornwall recaps chemistry and relation to energy to cells. Her hand motions help with my learning and understanding. Thank you.

two stars just for the effort. But its ore like reading fro book. Nothing different. Very boring. No interaction.

Great professor. Has almost everything needed for my course in Biochemistry.

Didn't explain clearly and concisely which each type of RNA was as well as providing its clear function. Additionally, it is best to provide the correct definition thus, followed by an analogy. Starting with an analogy of how the different RNA types can make the lesson hard to follow as well as, causing confusion in the actual definition of the term. This particular video was hard to gather information from.

4/5 also add on the replication bubble but as far as the other information well done i understood the concept

I like the practical comparisons used for better understanding and remembering the topic, makes it much easier and more entertaining!

Concise and to the point for basic understandment of the subject.

I was struggling with this subject in school and he explains it so thoroughly.

Talks clearly and explains all the key points so that you can understand the lecture in simple terms

Just on the point, Lecturio is what they say it is. Thank you Lecturio!!!

The topics were categorized and explained well with good examples

Studying Biochemistry lectures helps me to understand and hold in memory every each case,,, so this is the best ever

Thank you dear Ms Cornwall l easily grabbed basic elements and mechanism of cell biology with your videos Best wishes

Muy buen docente, se nota que le apasiona su profesion y la ejerce con entusiasmo.

I love it... 100% worth it... Made it simple and easy to understand!

It was a great lesson thanks for everyting short and briefly everyting.

A huge thank you to Prof Ahern! You explanations are very easy to understand and your lectures are a huge help to get a better understanding of biochemistry topics. Thank you very much!

I like Dr. Ahern's lectures, I think he is the best in this program. He's very straight forward, precise, concise and connects different points related to what he's talking. After seen these videos I went ahead and did a q-bank of a different program and nailed the ones related to this thanks to his lecture. Some people need to keep in mind that these lectures are not going to cover every single detail, but unlike lectures from others study courses, they do cover more than the basics. For broader information with specific details you definitely need to read textbooks (e.g. Guyton, Robbins, Harrison's) and " google" it up.

appreciate very the mechanism described in this lecture. Very informative and easy to understand

It’s not a bad lecture but it’s bulky stuff that isn’t simplified to hold ones attention, don’t get me wrong, it has its highlights but it could be more interesting.

Really good discussion. I would love Dr. Ahern to by my mentor

I really liked the videos they very clear and easy to understand , they best part is they are short and precise to the point .

The marcomolecules lectures are very good with excellent explainations of content

The DNA Repair lecture was not very clear at all.

Great lectures, very clear and understandable! Thank you, Dr Georgiana Cornwall!

It is a great parsimonious source for understanding the mechanism in which amino acids build into protein and how amino acids are broken down through metabolism into various molecules inside the body. The lecture also provides the structural frame understand the basics of amino acid regulation through metabolism.

The explanation is cristal clear with examples and illustrations. Good picture of ARN structure.

Great lecture which allowed me to understand the topic much better than I was taught

All the explanation are precise to the point...and covers all the important concepts

Explains concept very well with good analogies that further enhances my understanding.

The knowledge is systematic, but I wait for long time to get a answer to my questions. And I still get no feedback.

Dr. Ahern creates a great foundation by breaking down concepts and building on them throughout the lectures.

Dr Cornwall has the gift for teaching!! She explains things very well, thank you!

The professor is excellent. I like how he explains things. Some of the professors move their arms around a lot which can be distracting or spend the whole time looking down at the computer. With others it feels like all the do is read from the slides. However the biochem lectures are very well done and by far my favourites so far.

The module is complete but the questions can get too easy

I really enjoyed the video and it made me learn, also I liked that are short videos

They are so awesomely explained and very helpful thank you. I’d love the videos to have that ten second rewind or fast forward arrows like YouTube does, and then it would be perfect.

she was understandable! i liked her! i am so prepared for the next test we will be doing

Very concise. Great illustrations. Thank you. Thank you. Thank you

The professor did not do a good job explaining concepts clearly, went too fast, covered little material

there wasn't enough details at some points. The topics, for me, are a little tough and the techer wasn't seems to be confident with the material. although the slides are very helpful to understand the topic.

Concise, easy to follow, great drawings, post questions provide a good summary of key points before

Thank you for your knowledge and for spreading it in this way for us, the students.

I couldn't follow this lecture - it was not presented well at all.

amazing lecture, finally i understood the tertiary structure for the first time

The lecturer makes the topic interesting, easy to understand. One begins to appreciate how these things link with everyday human existence and how they play a pivotal role.

Good and informative, no bad comments. Good lectures and lecturer

Good, where are the rest of the organelles (like peroxisome)

Need lot of detailed explanations.. especially in videos. The teacher is really good but the script is lacking too much.

its good and thorough, also covers minor lipid types! good to learn

Simply explained with a little history that made it fun and also helps keep the connection to the content, So much of medical knowledge is facts and figures which can easily become blurred in my mind. The connection to history helps this content stand out in my head! Thank you!

Explains it completely from the start to the end , everything is clear and simple . The structure is very easy to understand.

Dr. Ahern, I appreciate the pharmacological and pathophysiologic connections you make when delivering your lectures. It aids retention and usefulness. I am a nurse practitioner student and can also see the clinical connection. I have administered Methotrexate to many patients. Thank you.

I love this app but can get a little confusing when the professor uses the wrong words or accidentally says the wrong thing. Do you not edit errors out? It’s a great platform just needs a few tweaks here and there.

Very high-yield. Thank you for underlining this moment, crucial in treating hypercholesterolemia.

Easy to understand and fun! Really useful! Great examples are provided!

I have taken biochem as an undergrad, grad. and post grad and I've never had anyone explain things as clearly. Dr. Ahern is one of the best teachers I've ever encountered. Thank you!

I am a student at Downey High and I really want to be a cardiothoracic surgeon, and I didn't know what to learn but I know this website will help me.

This is pretty good introduction! haha how to control the cell cycle

just basic to litle details course.easy to understand it.

I thought that this was very thorough and went over lots of the material that my current professor is going over. Some of the questions were either a little simple but reiterated take home points, or were left-field as the material was not covered in the specific video I just watched. Overall I would recommend this course to anyone struggling in genetics + read the comments because she does a great job in answering and clarifying questions you may not know that you had.

A+ teaching style and delivery thank you Dr Ahern for making a difficult topic easier to digest

I think it is an entertaining way to learn the history of Biochemistry.

Actually I saw the YouTube add . And I watched the lecture . The information is given in short and precise manner. Understood everything.

The video helped me understanding this topic with visual representation

I love this guy. The way he explains makes Biochem look easier

A very well presented and in depth explanation of biochemistry. Dr Kevin Ahern also responds very quickly to questions. Definitely would recommend to anyone struggling with biochemistry like I was !

I loved the correlation with margarine and butter, it helps to understand and remember the topic.

He is clear, short, and simplify the most important points

it is really amazing lecture & has been organized well thank you

I loved how I understood the bigger picture in the end of the lecture

Clear and Comprehensive explanation. Not too detailed but enough to understand.

he is very clear and is a nice teacher, and he use a appropiated nivel of technicims

I like so much the content of this course and how the doctor provide the information

I found this lecture very concise and easy to despite being quite basic. I have always struggled with understanding atomic structure and feel that it's due to information overload. This lecture provides just the right amount of information to build on.

I really liked this site ,and it's seems helpful for me . I am a high school student. I am in the 10th grade right now. I just want to become a surgeon doctor because I want to save peoples lives. I know that I have to right a commit to this site and I do not have to introduce myself for you people. I do not need to study this because I did not understand today's subject.I just want to be ready for the medical school. I hope this website will help me being ready and ,Good Luck.

I finally understood why we have Lineweaver Burk Plot and how we read it.

Concise with good use of slides and professional presence and dress.

P53 GeneRate this lecture P53 Gene Rate this lecture P53 Gene P53 Gene P53 GeneRate this lecture

Very useful for people who don't know much! Concise, and well explained!

Was very clear just speak very quickly, then I have to repeat the lesson to understand complete anyway its not important, I would like just when speaking about the oncogenes give some examples about the food that causes

I liked it very much because it helped me access materiel that I already new without further complications. It was very easy to comprehend and I will recommend this to everybody needing this for whatever the reasons you need it for.

Appreciate too much, because after many readings in the books, finally I understand clear having the big picture of this topics . Congratulations to the Teacher .

Very much explaining After I did this topics know is easy to undeerstanding

she looked like she was reading from a script and not focused or natural.

extremely helpful when the amino acids are divided in functional relevance.

Great lecture. You have a great and enthusiastic way of explaining.

Perfect way of explaining complex things. This is rarely seen by lecturers. Wow!

Amazing lectures. Simplifies complex pathways and process. Really fantastic! Watched every lessons.

she explains it to the point and doesnt waste time going around the topic.

This lecture was explained super clear and to the point. Thank you!

Well done! Very targeted information. For those that say it’s not as deep as their classroom lecture, it is not designed to be. Again,what we are supposed to get out of this course is the high yield information...and we are getting it. Thank you so much Dr. Cornwall.

Clearly explanations, every piece of knowledge that prof. Ahem shares with listeners is facilely absorbed and stays in the mind.

Attaractively and well explained video of serine protease catalytic mechanism that I have ever seen...Thank you..????

:) Thank you . everything in this lecture is clear. like it very much.

Very eloquent :) my favorite on this website! would definitely recommend.

thanks for your helpful for the all lovers of education

A good introduction. Very schematic and overall easy to learn basics.

Easy to understand...high yield information....great graphics,well done!

Easier to comprehend with the use of great illustrations. concise and crisp presentations

Made it very easy to understand. Thank you very much!

Almost no information really disappointing. Use Step 1 2018 page 46 ... Even a student could have presented the topic in more depth as it is important.

a tough subject, but Dr. Georgina made it very easy and palatable, thanks soo much.

I just want to admit that this tuition is a hard one and she made it very easy.

just excellent , the content and the preparations were realyy excellent and goes very easy.

I believe that she is a great lecturer but, the issue is the way of delivering the lesson and how much was she ready to record the tuition. anyway it was a good experience for both of us, she let me search a lot for the genetics to unwind condense informations :)

This is only the first lecture and the first time I am delving into biochemistry for the first time, so hard to say, but something about Prof. Ahern's manner makes me curious and creates a fine feeling of anticipation. Great for a first lecture.

Very disorganised way of explaining concepts It would be much better if things were presented in more detail and if the presentations were structured adequately

Concise and clear beginning in cell biology and homeostasis to warm up.

I was already following him before knowing lecturio. Nobody explains Biochemistry like him! Thumbs up!

it was described in a simple and easy way to understand, thank you.

This video did not really show Aspartic Acid or Glutamic Acid?

The lecturer did not appear confident looking into notes too often. Too many hand gestures are a distraction especially when not pointing to the stuff on the slides. The material was not presented in an easy or simple way. Made it more complicated that it actually is. I feel difficulty in continuing to the next lectures without understanding this.

He very easily simplifies things. So this is why I give him a five star review

Amazing, loved it very much. Easy to follow and clear.

amazing ! thank you so much dear dr.Ahern , i was always scared of biochemistry ,but its the first time i finally get to understand it and i owe it all to you. My committee exam will be in two weeks and im hoping to finish this course plus few more lectures from fat metabolism course. also special thanks to lecturio for preparing such a great learning system opportunity for us.

concise and straight to the point,exactly what I was looking for

I wish all professors prepared students for Biology courses with this explanation. Thank you for addressing this concept!

To the point, clear, precise, great tone and flow. Well planned curriculum.

Amazing lectures! Very well explained and effective videos. A perfect way to get a clear view of the subjects, very glad I found this.

Awesome lecture, awesome proffesor. My teacher spent almost 1 hour explaining that. Thank you Dr. Ahern

Nice succinct intro with basic overview -- key points are highlighted

I feel like she is just reading notes that she has been just handed over.

The presentation is simple, short and concise preparing students for more detailed content. I believe that this is an efficient approach toward a broader base of an audience. Thank you!

as a beginer i didnt couldn't understand anything the lecturer is talking about and the lecturer is way too fast

For the first time ever, I got AA right. Thank you!

I'll just say thank you very very very very much!!!

My name is Barbara, I'm from Colombia and I really like your videos Mr. Kevin, because I think the content is easy to understand.

informative course, to the point, easy to follow and understand, quiz questions are interesting

the course was good, the first video was condensed with a ton of information and I think you should maybe think about splitting this kind of videos in the future, I was finding myself watching other youtube videos to study this subject. it is always good to use plenty of different source of information to develop a wide perspective on a subject. but in this case, I want to rely on lecturio only.

Vitamin section is fine, concerned vitamins explained clearly and easily However, some water soluble vitamins are considered missing (eg. thiamine, riboflavin, biotin, vitamin C ) although they might be encountered in some other subjects; such as nutrition. Additionally, minerals are not touched in these lecture series at all Overall, it is a very good course for the material targeted, but needs to fill the gap of missing items

Pure gold indeed !!! Presentation of chemical compounds during presentations is very helpful.

Dr. Cornwall is very thorough and paces herself very well in relating core concepts.

Love him so far, clear concise and to the point and also very enlightening

most of the things i catch from animation while only little from lecture (for which i had to pause the video to read all those stuff written there, which is time consuming). mam's speech seems quite a kind of nervous, suffocating type

it is a very interesting materail, so clear an usefull and could recomend it without any question

Yea, these lessons site wide need more quiz questions. Only thing holding this site back from being outstanding.

Very well explained and detailed lecture, but it would be nice for better understanding to have some names and terms (e.g. Ramachandran plot) displayed in the video!

way too fast ????I really wish the teacher would talk slower as now I keep having to pause and rewind etc.

5 rating is what you deserve , i really liked the way you illustrate those key aspects

So much more simple than my lectures. Thanks for the detailed lecture. You're a life saver.

Direct , and easy to follow. The length of the video also helps.

"... and we know that the DNA was taken up because the plant grows tumors OR NOT..." Taking the term "tentative scientific language" to another level!! LMFAO >D

Great professor but unfortunately the details of this lecture are not important for USMLE Step 1

Easy to understand and the explanation are very clear. Thank you very much good job!

In my school we will take this lecture in 2 hours!!! Way too short and superficial

well done, explained thoroughly, yet concise. Having a minimum word count on a review is a deterrent; please change this.

THANK YOU Pro Ahern you're amazing! very well explained!

Professor Ahern is a perfect teacher and he makes everything so easy to understand

Needs more details, and take it slower so that we the audience can get a more thorough understanding of the topic (the video really doesnt need to be that short)

She talks too fast. Also reads too much from her papers. Seems like she's not sure of what she is teaching.

She talks too fast. Additionally, she reads from her notes too much, strikes me as someone who does not have a firm grasp on what she is teaching.

I found it really helpful. Your explanations were clear and easy to understand.

As much as your stories are interesting for the ETC gradient It does not fit my learning style. It would be nice to have clear scientific language about what's happening. I can't write a story on my exam paper. Perhaps this is just me.

Highly recommended lecturer for Biochemistry! I like his method, he is attractive teacher.

Easy to understand and very complete. Thank you for your time, helped me a lot

Thank you for the video's theses are really helpful. look forward to keep learning.

Feels like she is not comfortable with information she is teaching. Accuracy of information (and spelling!) is sometimes questionable.

very nice clear and organized lecture. thank you. it adds alot to my simple knowledge

Great Explanation !! I wish we would have had you as a teacher. :)

thanks for teaching me in such a clear, precise, and yet enriching way

Wow! Muchas gracias por todo el contenido muy bien explicado! Realmente fue muy interesante y, de gran aprendizaje asistir a todos los videos del curso "Introduction to Cell Biology".

Thanks for focusing on the "big picture!" The lecturer at my school bogged us down with the details, so it was hard to take in what the most important steps were

I Have watched only the free videos of basics of biochemistry as I seek to do Step 1 as an IMG. I like the smooth transitions and the questions at the end of each lecture. I seek to subscribe for the annual package soon.

excellent lecture. Cristal clear; not too slow not too fast, smooth transitions and a bright ending

prof Ahern is wonderful and funny! enjoyed all his lectures

It was very precise and up to the point. The presentation was interesting that triggers to study better .

very good lecture. pretty well organized and instructive. He has a deep knowledge of the material making me to pay special attention to all his lectures.

Very nice and informative lecture, easy to understand and remember

I have followed Dr Ahern through all the basics of biochem lectures and he has never failed to deliver.

Great job again Dr. Ahern! You have helped me better my understanding of these topics.

Great job, Dr. Ahern. Thank you for bettering my understanding of these concepts! Used as a supplement to lectures and powerpoints, your videos on Lecturio have been extremely helpful to me!

great lecture, very simple and clear. I've finally understood bonds!)) thank you!

Very good lecture, l consider that is one of the most complete themes that l´ve read ...good job.

very informative and well explained lecture. Dr. Kevin Ahern has changed my view of biochemistry.

Brief, understandable, high yield information explained with illustrative slides by Dr. Ahern

Very well put. Dr Kevin Ahern explains difficult topics in a very short concise and interesting manner.

I am a biochemistry student studying in the UK I found this so useful especially as a foundation in my initial year of study.

I love the visuals, her method of speaking and the transcript at the end

The combo of visual and review aided in maintaining info

This lecture and the one before were very confusing. You need to explain that the third energy level can technically hold UP TO 18 electrons (s,p,d sublevels) but it also fills up with the first 8 it receives. valence shells (energy shells) and energy LEVELS need to be better distinguished and not used interchangeably. Luckily, I knew the material and was able to straighten things out for myself using Google. How can I know that Lecturio will not have faulty lectures in the biochem module (material I'm not familiar with)? I am still within 10 days and am considering cancelling my lecturio subscription over this lost credibility in my mind.

It is very clear to understand. Great job Dr. Cornwall.

Prof Cornwall does a great job at presenting the material, catching my attention easily into the depth of the material while being precise with the content. Very easy to learn from :)

You make it much more easier. However, I still understand all important points. Thank you!

This guy deserves a medal. I wish I had a lecturer like this when I was in undergrad (or even now in medical school).

This entire series is the most eloquent and beautiful explanation of a terrible terrible subject like biochemistry I have ever seen to attended

She talks so clear, understandable.. just a little fast but i havent got bored.. Thank you..

I love it so much!!! It’s been a truly rewarding experience for me!

Good lecture, but not USMLE focused. This is more of a general biology lecture than a USMLE prep lecture. It seems to me that Lecturio is not making the difference between MCAT prep and USMLE prep. The lectures look more like MCAT prep lectures and not USMLE.

I like the way she expresses, you can easily understand her

Very good use of examples connecting to every day life.

Very helpful. Just passed final exam of Molecular biology and Biochemistry I-II with A+ Lectures are clear, made me understand the topics well sinceI had a good concept about the basics I could absorb more details and could recall immediately when needed. Highly recommended.

Hello Dr. Ahern. Your lectures were phenomenal, but for several of the lectures the slides did not correspond with your lecture (they were of totally different topics) or they changed midway into into unrelated biochemistry topics. It may be best to review them and adjust the errors. However, your presentation was so so good that I was easily able to follow your lectures with the downloaded lecture slides.

best prof in the world explains everything so good that even a kid will understand

Its a little bit dificult to understand but the information its complete and tables and graphics helps a lot

VERY CLEAR AND EASY TO FOLLOW! IT CAPTURED MY ATTENTION. ALSO LIKED THE FORMAT

Really great explanations of the whole process. Was not happy that I had to relearn Krebs and ETC but actually found these videos enjoyable and valuable.

Great enzyme analogy! Enzyme is the friend who puts his two other friends in contact with each other so that they can start talking and dating ;)

Nothing on how p53 relates to RB or how p53 induces p21 to inhibit CDK thus acting as a tumor suppressor by not allowing cell cycle progression. This info is found in the the First Aid for the USMLE so it is probably important.

I like the smooth flow of the subjects in this course and how they focus on small details that make you digest and understand the living human from very small details.

In terms of studying for something like USMLE, brief intro is fine! Such topics will not be tested on the exam but are necessary to build foundations for other future topics. If you are studying for other exams, this whole module may be a bit light on key information. Great as a refresher though!

Conveyed the process in a short &digestable way.I LIKED THE WAY OF presentation too.

Not bad, but need to identify the polymerases better, as in the replication of DNA and RNA...

Had so much difficulty learning the enzymes on the pathways. This way was easy to understand it!!

his teaching is clear and it is not allowing me to get even a single doubt

i could understand the concepts better. explanation was good.the charts were self explanatory. it made me feel bio chem much more interesting.

There is possibly a mistake in galactosa geometric formula in the lecture

I’m following this course as I’m attending this course at my university, it very helpful, but I wish it was as detailed as our class are.

I like the way you link things from one to another. Yuu made these lectures highly appreciated with the concise and comprehensive explanation! Thanks Prof!

really helpful i never found this data in any of my textbooks

This is not a USMLE 1 focused topic, an important material for the step, it's so superficial either the question that is a first order question. Need to going deep in the topics, we're not an undergraduate students.

Not my favorite subject but very well explained and understanded.

She broke it down to the very basic and helped me get a good foundation

The explanation is very clear, I'm early to continue watching more videos.

Understood the lecture clearly. Very impressed by how clearly he explains things.

Wonderful! An awesome lecturer, he just has a unique way of passing the message. Great work Sir

He explains it very well and at a good speed. He doesn't use to many difficult words so if your first language isn't english it's still possible to understand. Also whenever you have a question he answers quickly en thouroughly.

It is really helpful. I appreciate your kind efforts. Thanks verh much.

i like your teaching .sir. it helps me to understand the concepts clearly.

Excellent information and explanation, it's helping me a lot. Congrats, lecturio!

Me encanta como se enseña! Ya quisiera tener una profesora como ella en la Universidad!

I had to try so hard to follow what lecture was teaching, subject matter is quite abstract. All the same thanks for trying.

I had to try so hard to follow what lecture was teaching, i remember i enjoyed this better in med sch. All the same thanks for trying.

this topic is quite too cumbersome and lecturer didn't seem to be in control of material presentation

Great lecturer very knowledgeable of subject matter at an admirable pace. Needed this in depth type of lecture in med sch. Good job

Great lecturer very knowledgeable of subject matter at an admirable pace. Needed this in depth type of lecture in med sch. This guy is just good.... Great job

Great lecturer very knowledgeable of subject matter at an admirable pace. Needed this in depth type of lecture in med school because signal transduction in med-school was highly schematic . Good job

Great lecturer very knowledgeable of subject matter at an admirable pace. Needed this in depth type of lecture in med sch. Good job

Great lecturer very knowledgeable of subject matter at an admirable pace. Needed this in depth type of lecture in med sch. Good job

Great lecturer very knowledgeable of subject matter at an admirable pace. Good job

Great lecturer very knowledgeable of subject matter at an admirable pace. I needed this in med sch. Good job

Great lecturer very knowledgeable of subject matter at an admirable pace. Good job

It was just amazing, he was critic to give information and had the most important skills for me, and that is: perfect didactic. Had all concise information I needed.

He simplified the concepts and illustrated by a very nice way

First of all I would like to say that I really appreciate all of the effort by the professors and Lecturio to do great lectures, however, I would like to say, as well, that you need to focus on the exam format (In this case - USMLE Step 1). For example, in this lecture it was asked: "Which of the following is NOT a lysosome related disorder?" that is pretty good, because it has a clinical context with the subject, however this " lysosome related disorder" have never been taught by Professor Cornwall.

The explanations and images are well coordinated, making the review more interesting

Excellent delivery of content which was easy to understand Good use of diagrams and graphs to help explain key concepts

The explanations and examples were clear and right to the point

informative. good review for this basic area as it has clinical correlations

This lecture helps me a lot since i jave a hard time to understand.

Very clear what is going on. I understand it much better.

Prof Kevin Ahern makes even a complex signaling process easy to understand and the association with day to day events. I have loved his other lectures too. I literally used to hate biochemistry but now I’m enjoying it and that is why I have given his lectures 5 stars

very good outline and examples given in a step by step manner. Getting to like biochemisrty after years of putting this subject aside. Thank you.

Loved the lectures, especially the lecture on the electron transport chain. Dr. Cornwall had a really useful analogy of the ETC and kids (electrons and hydrogens) going to the prom (ETC) that really made the concept stick. Very good job!

It is very concise and practical it helps me a lot to understand in an easy way the collagen process.

The chapter about cellular structure has given me clear explanation and enhance my knowledge about the different functions that the plasma membrane assure. The course just makes my understanding of cell dynamic very straightforward.

I feel that the delivery is good but the content is not detailed enough, e.g. when talking about splicing, I think it would have helped to talk about what ‘snurps’ are involved and how this relates to initiation.

It's an excellente teacher! She uses easy analogies that you can memorize quickly and gives you a summary of your class (in my case). Greetings from México!

Excellent structure and content. Essential basics for chem and biol.Thank you.

Well organized backed with excellent methods of teaching & illustration. In summary, I found what I want in short period of time.

High yield facts and clear explanation, the fundamental elements and efficient route to master biochem!

I am new to this curriculum, however, I would like the lectures to be longer. I am hopeful that other lectures are much more detailed, e.g. gene regulation/expression. Lecturer is very knowledgeable, clearly.

Thank you very much! Those extraordinarily awesome questions help me better understand the whole thing with details!

I liked very much this course. It's very interesting and The good teachers.

Wow, these two amines are very tricky, thank you very much, Prof. Ahern!

Me gusto mucho porque pude repasar el tema sobre la homeostasis.

I liked the lecture and the diagrams, I can put 5 stars yet because I am unsure how relevant everything is. Pretty basic biochem, but it was a good refresher. The diagrams are helpful.

very good, is complicated, but i understand everything, she is a good teacher

I cannot believe I am just now finding this resource during my dedicated Step 1 period. However, I am so glad that I found it now, right at the beginning of Step prep, rather than later. I plan to use this as one of my main resources for the remainder of time up until my exam. I realized while reading First Aid that, although I had known the subjects very well at one point, that my foundation was not as solid as it once was. This is perfect for reviewing and providing the big picture for everything. It's also an amazing resource for providing the "why" and "how" behind all the small factoids written in First Aid which is just what I need. It's so much easier to retain the information when you actually understand what is going on rather than memorizing a 650+ page book of bullet point lists/facts. This is great. I was a huge fan of Boards and Beyond, but I have since ditched that resource and am fully focusing on this one since this seems a lot more comprehensive and better taught (though Dr. Ryan has also done an amazing job too). Thank you guys so much for coming out with such a well thought out and developed and thorough resource. This is going to make board prep so much smoother. If I end up scoring highly on Step 1, I will make sure to write a review on Reddit, SDN, etc raving about Lecturio.

I wish all the other professors had her didactics. Pointing clearly the goals of the presentation before and after the lecture helps us to mentally organize the subject.

I agree that it was brief if someone was looking for something more comprehensive. It was sufficient for me as I only required this to understand one lecture slide however not enough questions.

This guy is on top of his game at a ridiculous speed... I can't complain only if all others know their stuff like him there will be less confusion

it is really good ,some hesitation at the beginning but the diagram is very informative ,whopple hypothesis needs more explanation.

The course is informative and up-to-date, which is really important for me. I took my science courses before 2010; now, I’m preparing to take the MCAT. It is an excellent review of content.

Gooood job LoL and really a good story-maker????Thank you very much! Amazing, very impressive!

Thank you very much!! So funny and interesting! I laughed many times LoL also learned A Loooot!!!

I do not think there can be any simpler explanation of these concepts. Dr. Cornwall takes her time to explain these concepts in a way that they stick with you, and the analogies she uses engrave them into the medulla so that you can relate to the concept. You can't beat this! This is exceptional!!!! Thank you so much!!

First step to refresh and understand different concepts. Highly recommended.

The material covered a wide variety and having a non-science background it is clear and easy to understand.

This guy just knows his stuff, on point even with the speed of his speech he has mastered his slides. I almost got scared with the previous lecture in genetics but he managed to bring me back home. Very knowledgeable keep up the good work and add more clinical correlations.

excellent she is a very good teacher, the grafhics are didactical she explains in a very simple way, i like it

Care for details and passion/curiosity for knowledge are seen in this lecture. I gained a lot from it.

I LIKE THE PRESENTATION AND I LEARN . PROFF. USE A SIMPLE AND UNDERSTANDABLE LANGUAGE

it's not helpful for the new medical student.lecture should be more prolong and specific,little slow mood.

I like the fact that the lectures are detailed and Dr.Cornwall makes it fun and easy to understand.

Very profesional, why is it said that bacterial chromosome has a single origin of replication and eukaryotic multiple origins

The course was well explained. It is confusing subject matter, but she did her best to make it understandable. She is funny, energetic and lively

This is course is still challenging me but i can understand how abstract the concepts are i think i need an in-depth review of course

Thank you Dr. Cornwall, I really think genetics is quite a difficult concept so you are doing your very best, i must admit its very confusing at times i will need go over the concepts again.

I really loved it, because PhD Cornwall made it really easy to understand.

This lecture was excellent in every way, I must say DR. Cornwall is a Pro in intermediate metabolism. I couldn't understand this processes better in medical school than she has made me.

Brilliant. I recommend this course strongly if you want to understand this topic.

Based on explaination. I felt there was some lack of informations. In some area needs to be more profound.

Its really interesting subject made easy by an interesting professor. I'm not sure if that level of details are needed for the USMLE exam as I'm using the USMLE curriculum, if its not needed thats fine it will be for my future knowledge hopefully if i get to keep in my head.

Great lecturer who is knowledgeable about the subject. However the animations in both mitosis and meiosis would have been in motion so the explanations were tuff to follow. overall good attempt. keep up the good job.

great lecturer who is very knowledgeable about the subject matter, pitch, diction and pace is terrific. keep up the good job.

great lecturer who is very knowledgeable about the subject matter, pitch, diction and pace is terrific. keep up the good job.

great lecturer who is very knowledgeable about the subject matter, pitch, diction and pace is terrific. keep up the good job.

It was simply amazing. The knowledge I got exposed to was simply clear cut and delivered by an expert in layman's literature. I am keen to absorb more of Mr. Kevin Ahern's lectures.

The lectures are nice, simple & very well explained. I would definitely recommend this course to my friends!

This instructor makes this course enjoyable, and very easy to understand the materials presented here. I have already informed all my friends who are interested about going to medical schools about lecturio. Lecturio is a blessing to mankind.

I like how Dr. Ahern took his time to explain the topic in an articulate manner. Helped me understand the topic and want to learn it more.

Excellent lectures, you can understand in a few minutes the basics of difficults topics

Well explained she took her time tho but she did it well

El semestre pasado apenas y me di cuenta de todo lo que la enzimas y las reacciones significaban, ahora creo tener una visión mucho ma completa, GRACIAS

Batalle mucho para entnder mis clases pero con estén curso tengo un mejor dominio de el metabolismo y me permitió realizar una presentacion del tema ????

An excellent, brief and up to date piece of information, ideal for quick recall

Very easily to follow. The concepts are explained so that one who isn’t familiar with biochem can understand with ease.

Thank you so much Sir for brief description of all topics.

Well done by the professor with full of transfer sense.

the lectures is shallow; i think that more details are needed. it is ineffectual for the level required from the biochemestry course of the Med University of Florence. cordially gioia

couldnt understand a thing. Please try to use animation to explain better

Classes have an excellent quality, however there are small mistakes when you´re reffering to some specific molecules such as cAMP and cGMP because in some ocasions, you tend to exchange one with the other in just a few ocassions. Nonetheless, the overall course is excellent, with clear explanations.

The explanation is so basic and explicit, hitting all the important fact that, even illiterates would understand. Great lecture!

How I wish I had this when I first started medical school. The explanations were clear and concise. The use of simple words enable me to understand it well as well as the option to pause at anytime allows further internalization of the facts.

I am having my genetics exam soon and this course was extremely helpful to better understand the information. Thank you !

Recommend this course to any medical students doing pre/clinical Helps with pathways and understanding breakdown.

You can memorize or you can understand. Concepts are yours forever. Memorized lists of facts are gone the very next time you need to cram for another test.

Free trial makes lot of problems in watching the video .... Not properly organised app

u r so good like honestly amazing thank you so much professor

Excellent! Well delivered and full of quality information. Totally recommend this course.

Dr. Ahern was very clear and concise. Great lecture. Thank you!

Doctor Ahren. Great explanations and enhances my knowledge in biochemistry, i´d rather reccomend you tu use a lower velocity on your explanations because some of the students are foreigners and they probably may lose the idea. Nevertheless i´m completely satisfied with your video lectures.

Simplified the lecture in enzymes and i like how everything was explained in a simple but direct way. :)

Amazing lecture and slides explained very well and it was useful to have the slides downloaded.

I learned a lot about cell structure in the most simple and efficient way.

It is too much Helping. It is Awesome and helpful

I finally understood why keto diet is so effective :) Thank you Dr. Kevin!

The lecture were short and concise and were just thesame as what I needed to learn.

The lecturer uses great analogies to make concepts easier to understand.

This lecture was very educational, and well organised, moving from the basics to the complicated topics, explaining every topic step by step.

Explains everything extremely clearly and made all of the processes easy to understand. This was a great lecture series!

Excellent lectures. The professor speaks very clearly. He makes it easy to understand.

Very good explanation of concepts. Animation could be added for excellent explanation.

Every topic was clearly explained and I could understand them very well.

These lectures are good , but it needs improvement it should be more in details , and the actions are not mentioned in its orders for example first of all initiation then elongation finally termination ..

The lecture was very intriguing! Dr. Ahern is so well articulated!

I don't waste my time going to any biochemistry lectures at my medical school because I know that Dr Cornwall explains all of the content more clearly, in more depth, in less time. I always finish her lectures excited for the next one!

Brilliant! I have always found these topics extremely confusing at medical school, but Dr Cornwall is able to explain them in such a way that they seem straight forward and easy. This certainly replaces lectures for me! If anybody is unsure about trying this course, they should definitely try it! Dr Cornwall is the best biochemistry lecturer I have seen!

Dr. Cornwall hesitates a lot, and seems unprepared and unsure. Make people feel like she is reading the material and even not familiar with the reading materials. It is really confusing.

Very helpful on understanding the basics of the repair mechanisms.

The Good: Lecture: 5/5 Amazing Lecture! I learned a lot! The Not so good: Quiz:2/5 Only 1 question....and was not as specific as I would like it to have been. Perhaps consider having at least 50% of the terms discussed included in the Quiz.

The best professor! He makes everything easier. Very good lectures.

The subject is really hard... but the professor is excellent!

Wow! Never thought I’d be amazed by the clarity and succintness of the discussion. Packs into a few minutes what would take a four hour lecture to discuss. Defintely recommended these lectures to my friends who are struggling with biochemistry and don’t want to use the books so much.

A great lecture. I am a high school student and i struggle with biology. I get a better explanation from your lectures and I am not even a native English speaker. Thank you so much!

the lecture is good it educates on how bichemistry is related to other fields in life

thank you very much doctor kevinm very helpful lectures, especially vitamin D.

Thank you so much for beautifully explaining every single basic detail in chemistry. The modules covered up the required topics from the scratch to strengthen my basics.

Thank you Dr Ahern! Thanks to your clear and nice explanations With integrations I am finally starting to understand Biochem! You make difficult things look so simple and enhances the importance and intelligence of mother nature in our human bodies

Incredibly good! I have spent hours studying from the book and this is by far the most helpful in terms of deep,meaningful understanding of the subject.

I think this course is really informative, though I would like some more details in subjects like RTKs and G coupled proteins. And also please add English subtitles to this course! I'm not native and I found it hard to keep up!

The courses are very concisely presented, it is really useful for preping for an exam

I liked that she really knows what she is talking about and is able to explain complicated things with examples from everyday life.

Need more details Need to go slower But overall not bad

It is very clearly and enthusiastically explained. You make Biochem easy to understand.

As a medical student I found this series of lectures on enzymes extremely clarifying. Dr Ahern is a great lecturer. Thank you so much.

The lecturer is very good at getting biochemistry across. Well explained and understandable up and until here.

Needs more substance. This was barely long enough to be an introduction.

This lecture and the one before are not so well explained. The clamp loader part and the process of semi discontinuous replication need more in depth explanation

Professor Dr. Kevin Ahern is very clear in presenting. Love the short but very informative lectures. Would recommend to everyone, those with or without biochemistry understanding. Thank you very much Professor and Thanks to the maker of Lecturio.

Kevin must be the best teacher ever. He explains with a certainty only a person with many years of lecturing can. Simple, easy and fast, making complicated matters seem easy to learn. Compared to the slides i have in med. school, the content is the same. But this guy also gives the explaination in the same amount of time! His body language is also nice to watch as they are firm and open, kind of directing your thoughts, like a maestro. You just have to remember and do some repetition of EVERY detail he mentiones, it will for sure be on the exam. I also use his lectures to simplify my understandings from pdf files from school and heavy textbooks. I will recommend everyone to use this!! Also i love the quiz afterwards. 1rst year university medicine

it was really helpful,but a bit fast, good details and nice explaining

Fantastic lecture, just the amount of information I needed to cover and retain the topic.

It helps very much. Thank You. I will share with my friends.

Good clear concept review. Could use more specifics regarding cyclin and cdks.

Very clear summary. Would like to see more clinical correlations made.

Everything was on point .. Will definitely share with my friends.

I understood perfectly the concepts the way he explained them. He makes it ease to grasp

few things are missing like discoiling of histone protien and a sentence is not repeates

Very simple and easy to understand. Would definitely recommend this course.

Very concisely put, I love the lectures, very helpful indeed. Now all I need to do is work my ass off to get the dollars to pay for this awesome lecture. Thank you Lecturio!

I found the lectures to be very informative and composed of high-yield information for a relatively quick review of the subject. The only reason I give 4* is because of the few technical problems with the course; but, in regard to the course material, Lecturio provides a wonderful review of Biochemistry with Dr. Ahern.

Structurally complete, however, relatively outdated. Enough for medical study purposes.

Very good keeps on track with my textbook. Taking Intro Bio

It is really so good thing to take more information and I like so much the way of the explain for the teacher thank you so much for this helping for students

I love to use this great app to review my med knowledge!

I like the way that the AA are presented by a table between essentiel and non essential. I will use it for my memorizing process.

Great/clear explanation, definitely recommend to students. For those that complained, please describe what's needed to be explained, or just keep your pie hole closed. Being ambiguous is pointless.

no words can describe how much this was amazingly useful

great lecture! I still feel the need to fill in the gaps but it has given me an overview of gene regulation

I like the teaching style and material presented! It is clear and understandable. Thank you!

It's very clearly explained and very useful for my studies. I would like it to be a bit more detailed but not too difficult.

l am a pre-med student and after watching this lecture I decided I was definitely subscribing! Everything was explained clearly and I understood the concept completely.

Kevin Ahren explained the part very well. I liked the way he explaining this part. I am from business back ground.

Brief and comprehensive lectures. Really makes mechanisms and actors really to understand.

Both comprehensive and simple lectures, could use some more medical/clinical correlations, though.

Dr Georgina is amazing. Thank you for making all these difficult concepts easier for us.

i like this lecture. way of representing and explaining is quiet good.

It is fantastic to have a lecturer making a diffucult subject easy. Now i can not wait diving into some hardcore books about enzymes. Watching an inspiring teacher really makes a difference. This guy is also rather fast talking so you dont need to speed up, witch i do quite often. Also the pop quiz in the end just makes it so much more fun. It becomes a game. And thats great and enhances long term memory.

Very nice but there's some need of detailed explanation and then it would be perfect

Thank you so much Dr Kevin, this lecture series are the best that I have seen so far and explain very well, simple and practical a very complicated topic.

he is so good ... I am very thankful to you sir !!

it was perfect and describe a part of endocrine system very well.

A great, insightful lecturer. A Prof. at the top of his game. Miss his long hair though (checkout his youtube site)!

Easy to understand with the structure of the molecule. Very clear and straight forward.

Great Instructor. Clear, concise, very easy to comprehend. Dr. Ahern gives the "meat" of the concept. Not long winded.

Awesome job, I wish you were my teacher at my university! So clear!

I subscribe because of this professor. Great lectures and explanation. Nice job

What I loved the most about this lecture was how Dr. Cornwall actually took her time to explain the concepts discussed, and even used simple analogies to ensure that the information was easier to digest. This is something you find lacking in many professional lectures. Thanks again Dr. Cornwall!

It had been a few years since reviewing enzyme kinematics, this was a great refresher!

thank you very much, nice lecture, sounds great, well presented

It was very clear and explained well- the subject itself is usually hard to explain

it´s great conference, well explain, clear and simple. like ir a lot

very good course, i wish i have money to pay the all course

Thank you dr. Georgina Cornwall! Everything was perfectly understood with your lecture!

She spends half an hour explaining the steps of meiosis and doesn't even get into details... I'm not sure how she can manage to explain such simple topics in such a long time (it's half a movie time, for God's sake!). She should base her lectures on Molecular Biology of the Cell, by Bruce Alberts et al., AT A MINIMUM. Lecturio has many excelling lecturers; unfortunately, Dr. Cornwall is not one of them.

Stunning! Explanations are simple and very interesting, wish you all the best professor ????

The facilitators are very good because they motivate you to learn.

thanks. the lecture was very informative and concise for such a complicated topic

excellent work by professor to make biochemistry understandable for all

Thanks Dr. Kevin Ahern. Believe me when I say that I have a teacher who just read his lectures. I think that Biochemistry is a hard subject and difficult to understand because most of the things are just known perfectly reactions and structures. But your lectures have something else. I take some notes and it's easier for me to study the subject. Before I started with Lecturio most of my subjects I didn't know how to study. There is only one thing that I would like to suggest. I would like to know some facilities that teachers and students use for know the structures.

the plot charts are really confusing. takes a few replays to grasp a little.

Lecturer seems to know the material and is able to convey in a manner that is engaging

These lectures are made simple for someone like me who is very vulnerable to biochemistry.

I like the Lecture it explain many things but there are very important thinks haven't been explained like how to knockout some genes by using shRNA or siRNA. I know that you explain CRSPR which is the greatest method ever . But I think is necessary to talk about shRNA, siRNA and what the advantage and disadvantag because everyday in school we here about them and I think they need to coverd in this lecture. Thanks

Thank you Dr. Kevin Ahern!!! Sometimes you speak so fast, but these time was perfect :)

Don't replace her. Good OVERVIEW/REVIEW of the material at hand. Her pace is good. Her voice and expression and everything else is dynamic and engaging.

The professor was very clear and his tone was lively :)

Please replace her. Explanation is very poor, she hesitate a lot, and seems unprepared and unsure. It is confusing and in comparison to a lot of lecturers you have here, the standard is incredibly low!

Dr. Ahern is a fabulous instructor. He goes into just enough detail on all the important content and pathways, bringing everything into a more holistic view of biochemistry. A+!!!!

As it's my first lecture, I think I have to work a lot for getting great benefits from your great tutors. hence I had to give this rate. right now there are no such dislikes. well, thanks a lot for the kind assistance.

These lessons are brilliant enjoyed them so much I have bought some books by Kevin Ahern, PhD the questions at the end also reinforce learning.

I was impressed by the knowledge of the professor. However, the very short length of each lecture was disturbing and distracting.

Great lecturers and thorough explanations for every subject. After watching the lectures, I actually understood and retained because his lectures are extremely well organized.

this guy so good only amazing so much only omg nice nice

This is quite helpful. I am a pre-Medical student and I'm fully satisfied by the leacture. I'm able to cover all the syllabus. It's helping me to save time. I dont need all those notes n stuffs. Most important i can practise lots of questions! I'll recommend all Medical students to take this amazing leacture for once so that you'll be able to understand. Thankyou @lecturio! ????

Great professor, great explanations. This video was like a summary of important parts.

it was very good lecture it will help me in my med biochem class thanku

A ERY INTERESTING COURSE ,BUT REQIURES A LLOT OF STUDY TIME TO UNDERSTAND THE AMINO ACID CHEMISTRY. TO BE HONEST, I AM A RETIRED 85 YR OLD PHARMACIST TREYING TOEEP UP.

I really like the pace and clarity of this lecturer in how he presents the material. It would be nice to have animated pictures in signaling and transport. I also wish there were sections covering enzymatic catalysis & kinetics. Over all, very good! Thank you for making these

Great breakdown of these biologically important macromolecules. Amazing detail on presenting each macromolecule and distinguishing polymers, monomers and non polymers.

She is very detailed but yet not overwhelming with the lecture. It's been great help on my bio knowledge.

Not very hard to understand, sometimes a bit too "shallow". However most often very good. Even great.

The professor was very knowledgeable and presented the information in a clear and concise manner

Exactly what I needed. Straightforward and to the point. Linearly organized.

Very helpful Keep it up .. easy to understand . Lecture in a simple way

Hello though I learnt new things by the good explanation of the pathway but I will be happy if there could be mnemonics to remember then easily. Thanks

I rate this five stars because I like to go over it while I do other things and more than once.

The overview of biochemistry is really helpful! The images are great, and the lecture is really high quality.

it is a good course. easy to understand. I liked this course

I was hoping for a little more details about the chemical makeup of the topic, however, I like how the entire video is layed out and described.

The Dr Georgina did it very well she know detail about the subject matter andinet did not express about her and execelentroll model for me!

this Professor is really an encouraging one, he knows how to contact with his students, he has a deep knowledge, it is my first time to encounter this type of unbelievable professor.. more power Professor Kevin Ahern, from Philippines Honeylette Tayong :) thank you so much sir I really learned a lot from you, and aside from that you really motivated me to study deeper than I can ;)

Very good explanation and notes and diagrams. Dr has good quality teaching .

I like the way the instructor presents the material , and the examples she uses.

The lecture covered everything I needed to know for my upcoming test. I feel so much more prepared now!

This is professor is really good at explaining concepts and is thorough with getting caught up in the details

Dr. Cornwall is a good teacher. However the topics move quickly. This is great for biology majors needing a refresher. But for me it is helpful to take a second to restate an important concept or give context on what this process will impact in the future lessons. Helps the listener to remember it when you give it some context.

Seriously gifted biochem lecturer. One of the best on here in my opinion. He explains everything so clearly. Lectures are organized and images are really helpful!

Thank you very much for such a great lectures!Biochemistry have never been so interestig until now)

Well, I love the way Dr. G explains, however, the lecture on cell control wasn't the best and needed more explanations and needed to be more simplified . I put five stars because Dr. G has helped me a lot and made Biology a fun course.

This course really helped me understand the cellular structure, I learnt more from one of the 20 minute lectures, than I did in a 3 hour lecture at university, so these really help!

Good and clear explanation, Dr. G makes it fun to learn biology.

A very clear understanding of the basic concepts was developed by Kevin. Good examples and perfect illustrations made everything so easy and interesting.

Watching these videos from Lecturio is very much like being in my school. The difference is Lecturio is more fun and it encourages us every time we want.

very clear Explanation; I managed to understand mechanism for each type of Ihnibitors thus I can now draw the lineweaver plots.

Great constructive instruction at a understandable medical level thank you! Thelma Boshoff

With this introductory course, you will be exposed to the basic aspects of Biochemistry. Professor Ahern emphasizes that an in-depth knowledge of basic biochemistry will aid you tremendously in understanding life processes on a macroscopic level. This one course alone was well worth the one month payment of 24$. Every other course on top of that was an attractive but inessential addition..."icing on the cake"!

Excellent course! Whether you want to review biochemistry for a Board/National exam, or you are looking for help with a Biochemistry course. Professor Ahern details the fundamental aspects of biochemistry in a way that will make the importance of the many unseen molecules and processes stand out in all of their relevant glory!

The professor has a very clear explanation and teaches in a really dynamic way. The only negative thing about the course is that it's missing some essential biochemistry topics for graduation level like the citric acid cycle

It's the best. I really love how the doctor explains the concepts with simplicity. Biochemistry became much easier to understand. If it included clinical cases it would have been better.

Professor Ahern is truly excellent! Amazing choice. He clearly explains concepts and shows sincere enthusiasm for the topics. You need to bring him back for lectures on amino acids and the urea cycle as well as the electron transport chain.

The explanation given by Sir is very easy to understand and I able to remember for a long time.

Some parts that the instructor was going through were not gone into depth when they should have and some parts should have their own video.

Just an introductory lecture on any course enkindles a burning zeal to learn more. It is a perfect review lecture on the go and a better way to have fun while learning. A perfect definition of concise learning in a limited period.

I like it a lot. Good review. The slides for mitosis is the wrong one, ie different lecture notes

Very easy to follow, good flow and simply explained, exceptional professor! just wish the questions had explanations then I would give the videos a higher score .

I like this course ,well explained it does cover a lot . It really helped me to get a good mark and information

it has helped me build my understanding of biochemistry. looking forward to more lectures

Impressed by the knowledge of the presenter. However, had a feeling that she was asked to push/rush through some of the concepts in minimum possible hrs. Seems like some concepts needed more time to explain. Overall, I loved this series.

Love this course and Professor Ahern's enthusiasm keeps my attention. Being able to watch the videos over and over helps the lessons sink in. For the first time I'm enjoying biochemistry. Thank you for making these videos so affordable and easy to use.

Starting Biochemistry in the Fall and a little nervous..so I decided to brush up with self-paced lectures on Lecturio. Prof Ahern is amazing! His lectures make it easy to remember and the quizzes in each module force me to look up answers. So this is fantastic for those whose like to teach themselves. I also downloaded Biochemistry free and Easy and it complements the course nicely.

Since is starting this biochemistry, it's help me to remember some of the basic concepts that I have forgotten

I'm starting medical school on August 7th. I'm anticipating some material I'll be trained on in advance.

This is an amazing course! Prof Kevin has made every single details simple and clear. His deep knowledge and understanding of this subject is well reflected in his teaching style. The materials he used, are very attractive which makes it easy to memorize. I would definetly recommend this for both under and postgradustes students.

This course is well done. It's thorough. I'm reviewing things I've learned, and also moving on to more advanced material very soon. I wish I would have had this during undergrad.

Lectures themselves are very good and very comprehensive and detailed. It would be useful to know how much of the specifics of biochemistry are likely to be examined in board exams...I was under the impression board exams are leaning towards understanding concepts rather than specifics such as the mathematics/calculation of enzymes activity.

The biochemiThe biochemistry is one of the best because the professor Ahern is a terrific docent who makes one love the lectures

This is fun. I wish they were an accredited school. But they are good for prep.
