FOM II (Texas A&M)

the lesson is properly given, but requires a previous base, which must be checked back in books, even that is a useful video and the content is clear enough .

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

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

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

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

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

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

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

Thank you so much, Dr Thad. You're very clever in coming up with the 'gnomes' example, which is perfect for quickly understanding Acid-base. Thanks again.

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

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

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.

Clear explanation, and also the professor answers the questions clearly and fast in the forum !

Thank you! I appreciate how you explain this material. Thank you

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.

ok me gusto mucho esta leccion , gracias por hacer lecturio para estudiar

It helped me a lot to understand this topic better

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

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

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

Helpful vik of birth and postpartum doula of birth of a few days to get the best of

At first I didn't understand what the ED50 meant but I see the comment below. You made it so easy to understand. Thank you so much

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

lack of structure just got messy. it can be done in a much better way to follow the different pathways

I never understood this until I watched this video, thank you

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

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

Great way to remember the three portions of the ribosome!

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.

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

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

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.

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

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

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?

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

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.

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

Rather than giving us mnemonic, I'd rather had him explained. I had to go to Youtube to find out what this means and it took me a lot of time.

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

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

Awesome review , covering all the important concepts with clear explanation

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.

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

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.

This lecture provided me with so much clarity. Thank you

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

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

Es una excelente conferencia parte desde lo básico para entender la histología que es la biología lo recomiendo para estudiantes que están haciendo la materia de histología y biología del primer año de la carrera de medicina .Muchas gracias por esta gran conferencia

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

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

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

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

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

This review, expose the useful tools Anion GAP and Osmolar GAP, it is easy and complete.

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

excellent presentation explaining step by step important concepts at the right pace

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

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

Great explanation, It's great how the lecturer takes the time to guide our mental process. He´s so far my favorite lecturer.

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

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

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

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

The way he explains was easily to understand and memorize. Thank you..

Beautifully described. Clear and concise presentation. Your all lectures are brilliant

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

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

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

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

HE IS JUST THE BEST TEACHER THAT LECTURIO HAS EVER HAD IN HISTORY

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

Dr Raj is literally one of the best lecturers i know of

Dr. Raj is fun to listen to I love his excitement and personal stories.

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.

Excellent lecture. Hematology is often poorly explained. This is not the case here! Thanks!

Excellent lecture on this rare disease: not too much not too little. Also it's great that some societal context was given.

Simple straight forward info on Osteogenesis imperfecta. The medicolegal aspect is just well explained

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

Excellent lecture as usual: clear, concise, easy to remember. Thanks!

Excellent lecture, easy to remember the difference between the two diseases. Our teachers should get a Lecturio subscription.

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

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

I like the lecture because is easy to understand, the use of examples are really helpful.

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!

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

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

Teaches very well, makes everything easy and simple to understand.

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.

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

This was most helpful and extremely interesting. Hats off for explaining such a tough topic in an exceptionally innovative and engrossing manner.

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

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

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

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

Very precise and lecturer makes the subject interesting! Thank you so much!

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.

Magnificent lecture about polysaccharides and their functions for storage and release

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

adioasd oiaj doias ds dioas jdoias jdoas djoi asdjoia sd o

Definitely enjoyed this lecture. Concepts were concise making it really easy to follow. I enjoyed actually practicing the case study questions as it tested my understanding of the topic

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

I like the way you explained how this signaling process work

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

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.

One of the typical "pediatric" disease. Also hits multiple systems. It's good that there are several lectures dedicated to it. Thank you!

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

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

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

Great lecture as usual. The teacher succeeds in simplifying a complex topic for the practicing generalist pediatrician.

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

Hard to say what he is saying, even subtitles say that it is inaudible...

Possibly one of the best lectures on this platform! Dr. Raj truly is an amazing teacher, thank you for the lesson!

this video is short and easy to understand. Thanks Teacher

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

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

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

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

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

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

i really like it there is all of what i need thank you

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

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

It was easy to learn and the speed was perfecy

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

So easy to learn, this classes need more diffusion, thank you.

I love the course, it's easy to learn and to understand

Thanks... Dr Meyer very interesting and well presented information for rereading as a MD.

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

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

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

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

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

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

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

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

the explanation is complicated it could be simplified more better

it was very informative,thank you so much proff.big up

he is awesome; helps to connect the dots of concepts for me to make inferences rapidly

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.

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

This is a great overview of CYP and PGP issues. Drug biotransformation is a very complex topic and this is an excellent primer on some key issues. I hope to see more like this.

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

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

Very pleasant pace of lecture and clear explanation. Also love the quick and personal response on the questions on the forum. Really makes me feel like I am in the lecture hall itself.

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

sorry to say it is really not well explained or concept clearing kindly modify lecture

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

This is completely inadequate for the questions posed. The first question gives "you observed red gnomes outside the box on the left for both pH and HCO3" and asks for the condition. Verbatim from the lecture ‘’Respiratory alkalosis’’. Why? Cos there are two gnomes on one side." Yet the answer is metabolic acidosis.

Each RNA should be shown in the picture like above

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

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

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

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

Clear explanation in a logical manner, luckily I found this few days before my final.

I have learned a lot through her lectures, I love her lectures, she explains things very well.

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

simple and informative and I really like the way he uses his voice to keep us on point with him

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

I like it very much,before I was confused about this topic but now I can say that I am 100% clear

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 !

Really nice lecture, clear and easy to understand, with a lot of examples.

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

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.

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

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

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

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.

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

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

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

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

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

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

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

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

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.

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

I found this lecture illuminating. I think adding an image might help to clarify the solubility issue: AH can diffuse through lipid bilayer, but is less soluble in water, so would become "trapped" in urine, and the inverse for bases: B form being soluble in lipids, but not in water. Thank you for the great lecture!

The subtitles do not go according to the doctor's explanation

Short and interesting course. Binged it in one sitting. Ms. Cornwall is a pleasant lecturer.

I love her lectures ! Relevant for the USMLE and fun ! Recommended !

Dr. Shukle, I really struggled in applying the information from this lecture to the quiz. You have been great otherwise!

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.

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!

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

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.

The video helped me understanding this topic with visual representation

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

very good and excellent lecture.i like it.very good presentation

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.

Clean and clear. Simple explanations. He knows the subject for sure.

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.

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

The mechanism just summarises all the information into one picture

well put together esp the simple intro description of the skin

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

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

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!

Amazing and I learned more from his videos then in class.

I chosed to give it 4 stars, because I loved the way the lecture was eplained. I am not a native english speaker and therefor prefered the rather slow speed of speach. unfortunatelly there have not been any Control questions and that is why I only rated this lecture with 4 out of 5 stars.

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.

very confusing explaination. he didnt exaplin the concept properly such that we can grasp it. pls try to explain the concept properly

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

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.

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

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

Lecturio is Awesome! I am not a student but all the material I have been through so far is of HIGH quality! My best investment ever!

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

Excellent. I had no problem answering the folkow up questions. I've read about most of these concepts during a biochemistry course I followed earlier, which probably made it easier for me to understand interpretation of the curves in this video. Gives a good overview, so thanks! Sincerely, A Danish medical student

Some points are not stated clearly enough. Overall, good presentation.

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

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

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

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

Good Lecture, the curves were well explained. Wish they talked about Chirality a little bit:)

I really love these course! Great work breaking it down and offering the quiz it really helps!

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

very clear and visual, good speed, nice images and accessible vocabulary

As a lecturer myself in another field you make something that is difficult easy to understand for learning transfer = A+ delivery thank you

Beautiful calm lecture style delivery and explains concepts simply - thank you

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

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

The flow of the video is fairly slow, however, it's pretty detailed and informative.

Love you sir amazing is really good way of teaching..

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

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

Comprehensive lecture, suitable for supplementing your studies. Overall good quality and good for reviewing your studies.

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)

Dr. Wilson, you are my hero, you made this concept of acid base balance so easy for the first time in my life. Thank you so much!!

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.

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

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

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

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

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

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

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

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.

Shouldn't be popping back and forth between disorders- makes for very jumbled learning. Should talk through this disease in full then move on.

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!

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

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

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

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

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

I absolutely love this lecturer. He goes straight to the point, gives high-yield and applicable information (lots of information btw) in a summarized awesome way. 5 starts no doubt.

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!

He simplified the concepts and illustrated by a very nice way

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

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

This lecture helped clearing a lot of questions in my mind. Very well delivered. Thank you

I find that I get used to her style, I wish that all the courses be taught by her

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

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

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

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!

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

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

very good lecture, concise and high yield. very helpful for the boards

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

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

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

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

He is very good excellent clearly understand the lecture pharmacology aesthetic

Brief and to the point with the material. The visual was also quite helpful

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

I never would've thought such a complex respiratory concept would be simplified by a bunch of colored garden gnomes. Thanks Dr. Wilson!

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

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

Best pharmacology classes! Love the questions in between the lecture!

It's more efficient than reading the book.Excellent, it's easy to understand!!!

I really wanted to give it 5 stars specially because of the question pertaining to Fick' s law that was included, however the fact that Sir didn' t mention that all forms of diffusion are passive and the word Diffusion itself means being randomised made me give this 4 stars only.

It is too much Helping. It is Awesome and helpful

Just what is needed for the clinics and exam Bare minimum leads to better retention and the results.

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

helpful lec thumps up for me is better than the ophthalmo lecs by the same doc

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

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

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

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

it's amazing the example with the gnoms thank you !! easy to learn

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.

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 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

Need more details Need to go slower But overall not bad

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.

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.

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

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

Very interesting. Maybe ratio of aminoacid tryptophan metabolized to niacin and niacin consumed with food is good to mention. B6 can be pyridoxine or pyridoxal?

5 STARS TO DR SHUKLE Because 1. He speaks clear American English. 2. Lectures are very visual, concise and substantial. 3. He behaves and dresses very professionally. 5. You learn a lot in little time with quizzes between lectures. 6. It's so much fun and easy.

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

perfect !! i really liked the intro, but there is still some problem with questions..

the lecture could be better it was hard to understand all the curves.. and the answer for the question was not so clear

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

wonderful lecture by Dr Thad Wilson.....thanks to him,,,,,,,,,,,thanks to lecturio.................the topic is well understood.............

i think the topics of the lecture is not easy and it has a lot of new terms those need to be clarified more clearly

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

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.

Too vague; I got the same basic information/presentation out of lecture. I was hoping for more clarification in these videos on topics like dose-response curves.

Really enjoy Dr. Alverson's approach to teaching. I like how he goes into important details and remains enthusiastic and clear with his explanations.

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

clear and concise. provides a great sieve for distinguishing between the different sex development disorders.

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.

On the slide about respiratory compensation for metabolic acidosis, the compensation slope with decrease Pco2 level has a PCO2 value of 60 which should be 20. Becauase in respiratory Compensation for MA PCO2 slightly decreases That is just a typo, but can been confusing The lecture itself is very good

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

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

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

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

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

Very informative and simplistic in delivery. I eagerly look forward to the questions from this subject during the exams.

i understood the concepts right away. A great way of explaining from Doctor Shukle. Thank you

good good good pronunciation good good good pronunciation good good good pronunciation

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

Easy to learn using the box. I always struggled with this, even on my board exam. This box and explanation made it much easier for me as a visual learner.

This video was easy to understand. I appreciated how everything was stated in a simple manner. This allowed me to grasp the concept without confusing me. Keep up the good work.

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

Perfect, quick overview, ideal for the short presentation I am preparing on this disease!

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

blue ,red gnomes ,suoer ,really good lecture,clarified,simplified,nice

From what I understand, we advise patients taking Coumdain to AVOID eating vitamin K rich foods because it will counteract the effect of the drug.

Dr. Wilson does an excellent job in breaking down concepts of acid-base balance in the body and making it plain. He also provides some additional tricks/tools that you may not get in your regular lectures, but will definitely help on an exam. These lectures are top notch, just excellent!
