Lectures (WUM - 2nd year Biochemistry)

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.

Clear and straight to the point! Potentially difficult stuff becomes super easy with him!

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.

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

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.

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.

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

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

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

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!

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

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

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

Great way to remember the three portions of the ribosome!

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 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.

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

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

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.

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.

Just I need to get this course for my exam and i am progressing with Dr.Raj confidently...Thanks for all

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.

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.

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

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

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

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

man i really find it hard to understand the lectures

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 explaination was really good. And I am beginning to understand it

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

the presentation is easy to understand.. it is easier for me to understand the topic im reading in the textbook..

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

This lecture provided me with so much clarity. Thank you

I like it, definitely i will recommend this to my fellow classmate. Thank you Lecturio. Thank you Carlo Raj, MD

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

very good explain in simplest way , I am a physiology student, thanks Dr.

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

Again an excellent lecture from Dr Raj. I love this man to be honest

Dr. Raj's lectures are great for learning something. Best of the bests

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

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.

Very good class, very dynamic teacher, excellent for learning, 5 stars

Very good class, very dynamic teacher, excellent for learning, 5 stars

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.

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.

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

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

Dr Raj is my favorite lecturer on this site! I love his lectures and hope I see him more in future topics I need to study.

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.

making simple subjects more difficult, very bad examples and constant joking which makes understanding hard. the way he explains topics from last to first makes it difficult to follow and remember

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

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

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

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.

Great lectures, Dr. Raj! My 8 yr old convinced me to rate before I finished the lecture series.

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.

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.

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

It was informative lecture, the way of explaining the idea and make away to simplify informations was perfect Also putting every information in a clinical scenario was helpful I wish that doctor raj make lectures for all the subjects, his way in explaining is so so special, and he keeps it easier to keep the information for a long term

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.

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

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

he is very good, and fun! thankyou doctor carlo raj. best regards, med stud from indonesia

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.

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

A lot of repetitions which make it perfect to memorize, normal speed of talking - not too fast, not too slow

Exactly what I needed to hear while studying for Step 2. Thank you Dr. Raj for drilling it in my brain the "right" way.

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 .

Dr. Raj uses a conversational and repetitive lecture style that really helped me actually be able to learn and recall the material. I suppose some people may not like this taking a bit longer, but considering the fact that I was able to remember and learn the entire mechanism and pathology in around 20 minutes I think this style works well for long-term learning.

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

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 :)

This guy is awesome!, clear and straight forward. I love the way he motivates me to just keep the important data and let go unnecessary details.

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

Pure lecturing by Carlo Raj , as usually... jumping ahead and then circling back to the same point . 50% of his speech - just irrelevant noise/stupid joking.

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

very clear explanations and the questions helped me understand the content

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

Dr Raj is very wonderful! He made the most difficult topics to look simple and easy to understand. Nice lectures

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

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

Information is presented in easy to digest chunks. Love Dr. Raj's jokes too!

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.

Best lecture. I like the video.I read the slide with this lecture that help me to understand the our lecture.

I find Dr .Raj to be energetic, fun and I appreciate him taking the time to teach us concepts and foundations as opposed to blindly memorizing facts. Enjoying his series thoroughly!

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

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.

Dr Raj one of the best lecturer in the world

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.

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.

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

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

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

Professional, enjoyable and interactive. I also liked that the professor uses research based teaching techniques.

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

I LOVE the lecture but i'm having difficult time understanding it. I had to watch and stop and write to understand it.. maybe more diagrams? or break it down :)

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

I never thought I'd be able to understand dyslipidemias, I'd actually given up on it until seeing this course! Thanks, Dr. Raj!

not really engaging, hard to hear and understand. Didn't understand some of what he was saying

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

Each RNA should be shown in the picture like above

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!

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.

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.

Thank you for this lecture Dr Raj, it's now perfectly clear and I can't mistake anymore the different types of hyperlipoproteinemia thanks to you !

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

Brilliant! Dr. Raj focuses on understanding and establishes foundation knowledge for you to build on. Extremely helpful.

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

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

Best of all I loved it Tnx lecturio I am surprised Once more thank you so much. Big love.

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

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

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

He cares about teaching how to understand beyond the exams, and not just memorizing

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

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

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.

One of the most confusing concept is explained very clearly in a short video!!

Dr. Raj put all small pieces together in his lecture. His lectures are very detailed and he is not boring to listen. Thank you very much.

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

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

This topic from lecturio was absolutely lovely, this saving my life....Thank you so much Lecturio

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

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

Complicated processes explained in a straight forward and understandable way clear, understandable, logical, systematically, enjoyable, straightforward, focused to the main topic , nice

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!

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.

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

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

I love it. I learned quite a lot. Explained very well on a simple-minded person like me. And I was able to ace the quiz somehow. So yes, thank you very much!

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.

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

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

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

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

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

Very good! Helpful for repetition and revising the learned material! would love to see a pointer or a laser used in all of the lectures- it would make following along much easier. Thanks, Dr. Raj, great videos!

one of the best lecturer that i have seen. thank you very much,the way he is doing easy to remember all the facts.

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

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

In my country ( Cambodia ), we don't have USMLE exam but this course helped me to be more understandable and more practical in my career.

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

He doesn't follow through his explications, he jumps from one explication to another, without finishing the idea. He is very messy with the order of his explication.

Good good good! He knows how to combine physiology - pharmacology - biochemistry, and pathology seriously and how to interact with the audience in a funny way. He focuses on complicated concepts and repeats them many times to help the process of memorization.

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.

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

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

Thorough and patient presentation of an often problematic topic to a lot of students and practising physicians

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.

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.

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!

Excellent course, Im understanding hypercholesterolemia for first time in my life, and hearing all your videos Dr Carlo Raj

I could understand perfectly what blood is, the concept and which contains.

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

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

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

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

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

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.

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

I really found the teaching methods used here beneficial. He'd go through the pathway and emphasizing key steps, then point out where they'll be important down the line, then come back to continue the pathway. The repetition helped so that when he taught the disease I knew why it was resulting in that outcome. Really a fan of it. Also, keep the memory cues coming.

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

His fluid, conversational presentation style really makes it stick. I do not want my classmates to know about him.

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

It’s conceptual and easy to understand & just love the way dr carlo raj sir teach. Thanks

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.

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 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

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.

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.

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

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

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.

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.

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 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

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

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.

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.

Liked but another lecture not opened yet so not liked

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 ????

I am using free version and trying to see how good the videos are. So far all the videos hv been so clear and understandable including this video. Thanks lecturio for your great work.

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

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.

Helped me a lot understanding this subject! Carlo Raj's videos har really good.

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.

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

This was a good course because the lecturer gave examples and explanations.

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

Very informative and organized , keep the good work Thank you

Highly recommend this lecture to anyone studying cholesterol synthesis (biochem/pharm/patho/etc).

This is about the best lectures I have had all my life. I like it very much because the lectures are very explicit, The approach is fantastic. And the tutors are very experienced. They have a full grab of the subjects they teach. The team is like a conglomerate of experts from all fields of medical science. It has really helped in my studies in medical school. With Lecturio, there's no dull moment. It's actually a huge privilege for those of us studying Medicine and Surgery in Africa. I recommend Lecturio for everyone who want to excel in medical practice all over the world! Kudos to all the erudite tutors in the house! Hope to see more of you in Lecturio videos. You're all wonderful! From: APATA OLABANJI SYLVESTER COLLEGE OF MEDICINE UNIVERSITY OF LAGOS, LAGOS, NIGERIA. WEST AFRICA. (e-mail: olabanjiapata@yahoo.com)

Very complete and straight to the point, better than when my teacher explains

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!

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!

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

I understand, but I think, the lesson needs drawings and diagrams, but is very well, thanks

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.

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

-There was alot of jumping ahead and then circling back to the same point which made what should have been a 19 minute lecture, took about an hours lecture with all the pausing, going through transcripts and even looking up certain references myself to complete this lecture. The whole point of lecturio is high yield learning in a timely fashion. I appreciate the effort done and liked his style of teaching enthusiasm, however there needs to be less going off on tangents before the point has been made.

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

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

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

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

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

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

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!

no words can describe how much this was amazingly useful

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.

It needs more clinical correlation with diseases in the IV fluids For example, when to use normal saline or when to use dextrose this will make our understanding better

Explained easily and good diagrams. Good at pointing out key concepts.

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.

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.

great great lecture!! thank you so much Dr. Raj :) one of the best lecture i have ever watched.. you made learning so much fun :)

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

He is really good not forgetting his sense of humour makes the lecture more interesting. Wish to become a doctor like him near future. God bless Carlo Raj. Keshvinder Singh from Malaysia.

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.

wow... physio, patho, clinically.. all comes together. It is worth...

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

Good attempt for explanation of such a wide and tough topic

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

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

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

Dr,Raj you are awesome teaching skills better than my university professor,looking forward to see more of your videos. Regards, Raj Patel

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

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!

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.

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

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

Excellent Integration with Biochemistry that enables long term retention of what was learned in the first year of medical school.

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

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

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

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

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

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

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
