Love the videos man great work.... i just wanted to make a couple notes... you set that the cell you were taking as an example was a hepatocyte so hexokinase has to be called glucokinase (they do the same thing but one has grater affinity then the other for glucose and higher rate of phosphorilation adding to that hexokinase is located on all tissues but beta cell of pancreas and hepatocytes where hexokinase is found) ... the aldolase in this pathway remember is aldolase A since aldolase B is found on the fructose pathway... and a final note phospho-fructo-kinase has to be called phopho-fructo-kinase 1 since we have a Phospho-fructo-Kinase 2 which its product stimulate the PFK1 action.... Anyway this are minor notes but for exam purposes i think worth knowing... keep up the work is wonderful.... cheers

A suggestion. Your videos are very good. But they'd be a little less confusing if you mentioned where your straight lines indicate only bonds and where they include less important carbon atoms as well. For example, in citric acid, there are 6 carbon atoms. The diagram you use shows 4 carbon atoms (that's what I first thought, being someone who studies organic chemistry). I agree, this representation makes it a lot easier to visualise the cycle. I'm just suggesting that you mention this somewhere because it gets confusing. A side note, a list of the actual structures in the end, red dots for the atoms -- anything. It's a pity to have to stop and google the full structure of every molecule in the cycle. GREAT JOB THOUGH! You're channel is really useful. I appreciate the sheer number of topics you've covered, the accuracy of the information you present, and goodness, the neatness! Thank you for putting so much time into this!

@lolamoon72965 жыл бұрын
Daniel Frieka you would have a total of 4 atp in the whole process of cellular respiration, but within that cycle of cellular respiration you would have only 2 net atp. You have to remember that there are 2 pyruvate molecules created after glycolysis occurs. So both pyruvate molecules must go through cellular respiration process thus creating a total of 4 ATP after the whole process occurs. So 2 atp molecules created for each of the 2 pyruvate molecules.

@joerebman58579 жыл бұрын
Just a quick question: you've drawn the glucose molecule in beta conformation, rather than alpha... Is there a specific reason why? I understood that our body doesn't metabolize beta glucose (reason why we can't metabolize cellulose). So, shouldn't the anomeric carbon be anti to the chiral carbon? As a side note I love these videos and think they're awesome.
@kintuckyee41717 жыл бұрын
Hi Joe, the glucose monosaccharide free in solution is free to undergo mutarotation between the two alpha and beta anomers as well as its linear form, they all exist at equilibrium because the reducing end of glucose is not stuck in a glycosidic bond. Cellulose on the other hand, is non-reducing (anomeric carbon is involved in a glycosidic bond in the polymer) and therefore cannot undergo mutarotation. In all, the conformation that you draw glucose in doesn't really matter because it's in equilibrium with other forms of itself.

If most of these reactions are reversible, how do these enzymes know which way should they perform them? What stops them from performing them backwards and "undoing" the work of other nearby enzymes?
@JaCollado339 жыл бұрын
Bon Bon The way I understand it is that basically the body detects, or "reads", the amounts of inhibitors or stimulators in the body. For example, in the case of Pyruvate Dehydrogenase, which turns Pyruvate into Acetyl-CoA, you will have the body pushing this reaction forward if there is a high presence of substances like CoA, NAD+, Pyruvate, AMP, and Ca++. All of these show that the body is low on energy and could use more production of ATP, starting by converting Pyruvate into Acetyl-CoA. However, if the body reads that there are high levels of Acetyl-CoA, NADH, ATP, and Fatty Acids then it won't produce more Acetyl-CoA and simply preserve the Pyruvate. I can imagine it is a similar mechanism with reversible reactions. I recommend you look into Positive and Negative Feedback Mechanisms, which explain this concept much better AND it explains them in regards to enzymes and what not. Good luck.

At 7:50 NAD is reduced to NADH? Reduction refers to gain of electron ,right? i thought NAD loses the electrons (Oxidises) and NADH accepts that electron so that it can use that electron afterwards in ETC. Please correct me if I am wrong =(
@gaberlunzie2138 жыл бұрын
+hunter sikari In case you still haven't looked into this in the last four weeks, I'd be happy to answer your question as best as I can. Whenever I get confused, I always come back to the charges to reason through it. Consider the oxidized form of the NAD+/NADH system, which is the NAD+ component. When it becomes reduced, there is the addition of an H, yet the overall molecule ends up neutral in charge, unlike the previous +1 charge in the oxidized component. Think about that. That means that there is a more negative charge in the reduced form (NADH) than in the oxidized form (NAD+). That's how I remember the difference. A more negative charge indicates the addition of more electrons than protons, which fits with the entire narrative of reduction. If you can follow this kind of logic, you'll always be able to work through redox reactions without too much difficulty.

@crossingthemountain8 жыл бұрын
Glyceraldehyde-3-phosphate is drawn wrong. Should not have the right sided -O group.. An aldehyde has an -H. When Glyceradehyde-3-phosphate dehydrogenase works it to 1,3 Bisphosphoglucerate, you therefore show no source that NAD+ gets its H from this error. The subsequent 1,3-Bisphosphoglycerate does essentially result in the "hydrogen" from the earlier step being replaced by the -O-P you show, but it's only by removing the H (hence the name of the enzyme as a "dehydrogenase") to then having -O-P. You should have corrected this, as so many people refer to your videos. But my guess is you are already through medical school so you don't care anymore..

Hey, I've been going down this whole Biochemistry playlist. It's really good, it was especially mindblowing in 2013/2014 when you made them. But now I can only really recommend you make all these videos over again. Different colors between your base drawing, the names of molecules, the chemical structure diagrams, the products of reactions. Just to have visual aid in making everything distinct. They're really good videos, have been working for me for 5 years but I can't help but think you could just do them WAY better now with all the experience and also just eliminating all those little mistakes that start to accumulate along the way. You have more than a handful of errors on protein and enzyme names, product results from pathways - it gets a little annoying and jumbled and in the way of learning material. For the 3 or 4 videos on fatty acids and ketones you start to write a little more text than usual, it's not a big deal, but shy away from it - takes away from the beautiful visuals you develop. Also, I understand you can't zoom out and give the whole picture for creative rights purposes, but maybe give us better zoom out of individual sections so we actually GET the big picture a little better. Hope you decide to undergo this mission, I know we'd all be grateful, and future students as well.
