If you made an MCAT series like this you would be hugely popular. Thank you for the visualization!
You need to keep making videos like this! Your visualisations are out of this world, and make things so much more easier to comprehend ⚛︎

I was a little leery of this video at first, but it helped simplify glycolysis for me. It didn't get me 100% there, but it was the best I'd seen yet. Cheers, thanks!
Perfectly clear. Thank you.
great visualization and explanation. simple and precise, thanks a lot!
What a BEAUTIFUL representation thank you!!
Well Done! One of the best videos I have seen.
Your method in explanation is excellent method! Thanks for your videos ,keep going.
Thank you so much. This is just what I needed to review for my test.
What an animation 🔥 concept clearned in 3:20 mins
This is great, thank you!
Thank you so much for this video saved me so much headache.
Thank you so much.
thank you so much you make it 100times amazing clear i hope you contenuiee this vedios ✅
Thank you!
U know what ...u r magical..plzz.do not stop making such videos ..we need ur help mam❤️
Wow! What a great video!! You should make more of these. Maybe one about Fructose 2,6 bisphosphate regulation - it is a real doozy.
thank you! my biochemistry textbook is so convoluted and wordy that it's hard to follow. Your video made perfect sense
you made it easy. thanks alot
Short & informational thank uu🔥🔥
This is great
thank you, couldn’t find a good one in German so had to watch yours!
this is good thanks
great thanks alot
thank you so much this visalisation made it so much easier to understand what really is happening. in the las part of the video you say 1,6BPF is an allosteric effector and that when it binds it increases the second half of the reaction but you dont mention what it binds to to increase the rate and why. please do explain.
Thanks.
I think animation study is the future of general education
really helpful! I'm having my biochemistry of glucides and lipids exam in 3 days and I have problems figuring out their regulation :(
this shit is fire!
You should post more
Amazing video.! Just wanted to ask which book are you using as reference?

I don't actually use any books for reference, I learned this from my physiology professor who made his own slides. But if you're looking for a good textbook, I would recommend Principles of Human Physiology, 6th ed. by Cindy Stanfield. Thanks for leaving a comment, and good luck in your endeavors!

Thank you so much! why if the cell is low in energy would she accelerates the production of f-1,6bp?

F-1,6-bisP is an allosteric regulator for pyruvate kinase, which performs the final step of glycolysis. When we speed up the activity of pyruvate kinase, we speed up all of glycolysis. This is due to Le Chatelier's principle. When the cell is low in energy, we want to speed up glycolysis, because this will produce more ATP for the cell to use. More F-1,6-bisP = faster glycolysis = more ATP for the cell. Does that make sense?

@@lauraslusser8710 Yes thanks ! And this is due to the fact that it will consume less ATP for the synthesis of F-1,6bisP than the quantity of ATP produced ?

@@annaelle_stasia Yes, exactly. Glycolysis costs 2 ATP and produces 4 ATP, for a net gain of 2 ATP. Glycolysis also produces 2 NADH (which will make 3 ATP each via the electron transport chain). Pyruvate, the final product of glycolysis, goes into the Krebs Cycle to make more NADH as well as FADH2 and GTP. So even though we're investing a couple ATP to get glycolysis running, we're making way more ATP than we're putting in. Have a great day, and good luck studying! :)
1 question..if ATP is low and AMP is high shouldn't it try to conserve ATP instead of depleting it further?
