That's not correct.

AZ · Answer

This is glycolysis. Do you see NADH or FADH being used to make ATP?

AZ · Answer

Remember, NADH and FADH will give off their electrons and that energy is used to pump protons across the membrane into the intermembrane space. That proton gradient is crucial in synthesizing ATP from ADP

AZ · Answer

So does that occur in Krebs cycle or the electron transport chain?
