SLU - Molecular Foundations in Medicine

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!

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

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.

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

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

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!!

Recomendo pra todos que querem saber melhor sob Medina das universidades

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

I wish there were more foundational details included. I think Dr. Cornwall presented the material with the expectation that the listener already has a solid foundation in genetics.

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.

Unfortunately, Dr Cornwall confuses an already confusing topic. Waste of time that i don't have

I understand that medical genetics is a difficult course to review but improvements are definitely needed in the following areas: 1. State and simplify definitions. Too often i need to refer to Google for a more basic explanation. 2. Please stop assuming basic knowledge is still fresh. I haven't study genetics in 7 years and i have forgotten EVERYTHING! So, along the way and with each new concept please give some foundational information.

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

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

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!

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

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

Literally worst professor ever, she seems so desoriented and feels like she haven't even prepared the class

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

Excellent lecture, very clear and well explained. Thank you so much!

Great way to remember the three portions of the ribosome!

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

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.

Excellent summary and overview. Read the concept pages for more detailed info.

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

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

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.

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

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.

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?

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

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

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.

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

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

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.

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.

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

I liked the course ,but a little more explination is needed in each of the clases

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!

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

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

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.

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

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

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.

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

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!!

Very good - thanks so much! Really helped to get my head around these.

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

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

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!!

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

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 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.

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

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.

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.

It's well presented and relatively easy to understand. It has helped me understand various concepts

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

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.

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.

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

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

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!!

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...

Excellent lecture. I now feel more comfortable with recognising inborn errors of metabolism.

Excellent lecture, it makes it easy for the mind to grasp the concepts. Thanks!

Excellent lecture. It's a complex topic and once more it is made understandable and memorable. Thanks!

Excellent lecture. This is a difficult topic and it was made very clear, especially the mnemonics.

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.

i like but the fomr like the professor express can distract a little

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

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.

I use Emery’s Elements of Medical Genetics 15th edition as primary study material, which i recommend for anyone to use. I decided to take this course as a supplement and ended up confused and annoyed. Simple learning objectives of this course lectures are harder to understand due to poor explanation and as far as i can tell the professor seems stressed, disoriented and confused herself. Lectures need a rework. Despite that, the articles are pretty good and helpful, PowerPoint slides are useful to an extend.

The introduction provided me with the basic concepts of genetics

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

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.

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.

The objective was to mention which diseases are AR and it was covered correctly

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 .

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

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

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

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

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.

Most of it was good and understandable but towards the end, it became quite confusing to follow along.

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

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

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

very clear explanations and the questions helped me understand the content

i understand it though, you just need to concentrate on what the prof is saying and correlate well with the diagram then youll understand

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

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

this video is short and easy to understand. Thanks Teacher

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

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

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

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.

Interesting and informative! Expounded well on complex concepts and gave a riveting lecture.

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

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

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.)

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

I would like to inform you that from 3:54 onwards there is neither the transcription nor the translation in other languages. I hope you will solve it as soon as possible because some concepts I cannot translate from English into Italian. Thank you in advance

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.

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

Well explained and easy to understand the concept. I'm on the right track and enjoying the course.

the explanation is complicated it could be simplified more better

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

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

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.

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.

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

the explanations provided for each disorder weren't very thorough nor well explained

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

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

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

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

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

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.

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

Very clear lecture right on points. Thank you for making complicated concepts straight forward.

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

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

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.

I believe the term is entropy is misused in this 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.

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

need another resource for this topic as these lectures have confused me more

if the professor says she gets it confused when lecturing she should not be teaching it.

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?

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

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.

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

The lecturer is very thorough and makes the series interesting

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

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

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!

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!

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

The DNA Repair lecture was not very clear at all.

Great lecture, Dr Georgina explains clearly what we are required to know

Helped me understand better some concepts as she explained clearly

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

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

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.

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

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

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

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.

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

Excellent ! I finally understand the topic after forgetting it many times ! Much better than First Aid !

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

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

It helps me a lot with my presentation, I was having a hard time understanding this topic and after see this lecture it becomes easy to explain. Thank you so much.

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.

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.

Gives you the basis and covers the necessary topics for a good understanding .

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

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

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.

This particular class video is not very helpful at all. I feel like genomic imprinting can be explained more efficiently and more clearly than what is portrayed in the video.

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

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

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

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 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 in-depth discussion of X-linked inheritance. A very good resource for studying for exams on human genetics.

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.

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

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.

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

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

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.

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.

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.

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.

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

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.

You do a wonderful job of clearly and concisely breaking down concepts.

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

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.

Genetics generally is a very confusing part, I think she made it quite interesting and I grabbed a whole lot

The explanation of concepts were precise and focused. I like the pictoral representations I'll recommend the lecture to my friends, who are taking USMLE Step 1

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

I needed an update on genetic like this one, i like the way is shown every part and all the details within, i recomend this article to everybody.

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!

lectures are very exciting and informative provided someone have basic knowledge of genetics. With reference to USMLE, I am afraid to say that is it is helping.

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)

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.

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

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

Its hard to pay attention on her lectures because she always pauses to read her notes.

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!

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.

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

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

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

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

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

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.

The lecture are awesome. It is just easy to understand Thank you very much!

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.

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.

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

Not my favorite subject but very well explained and understanded.

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!

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 sch. Good job

Nice intro to genetics, subject that's usually scary but very well carried out. thank you

great lecturer with an incredible pitch and clarity but this subject rather fees boring and i tend to get the post lecture quizzes wrong but its all good. I need to read elsewhere but all the same keep up the good work.

great lecturer with an incredible pitch and clarity but this subject rather fees boring and i tend to get the post lecture quizzes wrong but its all goo. keep up the good work

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

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

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.

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!

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!

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.

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

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.

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

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 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

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.

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.

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.

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.

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.

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 ????

Good content, I like this course, but this particular class could be a bit clearer

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.

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.

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

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. :)

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

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.

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

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.

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 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 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.

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

Need more details Need to go slower But overall not bad

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

I really could understand this lecture easily. Even the mid time of lecture gives questions are more helpful for interacting with it.

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

Great Job, I really enjoyed the lectures! very easy to follow!

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

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

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.

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

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

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.

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.

Presenter explains the medical relevant aspects of S-G disorders in a logical sequence.

Great series on the medically relevant aspects of diseases affected by genetics.

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´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.

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

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

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.

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.

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!

Though it was good. Be patient w/ Imprinting the slides in Prader Willi/Angelman give a good visual of what it is.

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.

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

Good lectures, would be more helpful if there are practice questions and further readings. - first year medical student.

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! ????

These lectures (all of medical genetics) was really useful in connecting your knowledge. It is great how general theory is connected to the most important genetic diseases - very useful

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

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

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.

They are good..But lengthy..I will take take lecturio for my step 2 also

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

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.

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.

The course didn't deliver the main message I was searching for. I hoped to find a more concise and direct material for each topic. The Genetic Course did not help at all for what I was searching. I was hoping for high-yield topics and a more direct delivery of the material. We have too little time.

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"!

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.

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 .

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

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.

Since is starting this biochemistry, it's help me to remember some of the basic concepts that I have forgotten

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.

The biochemiThe biochemistry is one of the best because the professor Ahern is a terrific docent who makes one love the lectures
