It covers the 4 principal stages of cellular respiration such as glycolysis, pyruvate oxidation, the kreb’s cycle, and the electron transport chain. It also covers anaerobic cellular respiration such as lactic acid fermentation and ethanol fermentation. This video contains plenty of examples and practice problems.

I have a question. During the pyruvate phase, when O=C=O is broken off pyruvate and becomes CO2, why is that considered pyruvate oxidation if pyruvate is losing oxygen?

@obinnaagu4144 Год назад

I think the main reaction is pyruvate dehydrogenase, but pyruvate oxidation is a reaction under it

Hi! How many ATP molecules produces from the breakdown of one molecule of pyruvate to carbon dioxide and water (the enire proton gradient of mitochondrial inner membran includes too for ATP production and ATP-synthase has 6 c-subunits).

For Question 20 (T/F) (1:33:00): The questions is: The investment phase of Glycolysis yields 4 ATP molecules per one molecule of glucose. This question was marked as True. But I thought the investment phase of Glycolysis consumes 2ATP and the payoff phase makes 4 ATP which results in the net ATP produced being 2 ATPs. Is this a mistake? Or am I not understanding the question correctly? @theorganicchemistrytutor

@SHARIFAHZAINABBATRISYIASYEDAHM Год назад

At 59:20 wouldn’t it be 4 ATP molecules as glycolysis actually occurs two times, once for each g3p molecule?

@OreoWaffles44 2 года назад

yeah i think it was a mistake on his part. glycolysis produces 4 ATP molecules but you gain 2 ATP molecules; considering you spent 2 ATP molecules to produce 4:)

@marigeo24 2 года назад

@42:50 If 1 molecule of NADH activates 3 complexes and therefor produces a net of 3 ATP, why does 1 molecule of NADH2 only produce 2 ATP? Yes it activating 2 complexes, each of which produce 1 ATP when activated, but there are 2 Hydrogen atoms in one molecule of NADH2, and of course 2 are lost when it is oxidized in complex 2. Why wouldn’t 1 molecule of NADH2 (emphasis on the 2 at the end) produce a net of 4 ATP? (Each Hydrogen activating 2 complexes. Therefore 4 activations in total) Am I missing something? Thank you for your help in advance

@afkjj140 9 месяцев назад

This was really great; I just have one question no videos seem to answer. Where does the ADP come fromm?>????????

@4everThoughtful 8 месяцев назад

ATP/AdenoTRIphosphate has 3 phosphates; TRI=3 (AdenoTRIphosphate). ONE of the Phosphates is cut off from the ATP by an enzyme (Hexokinase) and attached to the Glucose molecule. Now, it is no longer an ATP because it lost/gave up a phosphate. Since there are now only 2 phosphates, it’s changed to the formula ADP/AdenoDIphosphate. “Di” means 2 I hope that this helps you.
