Answer:
3 moles of Pyruvate entered CAC
Explanation:
2moles of pyruvate gives 34 ATP MOLES
Hence 51moles of ATP willl give 51*2/34, which is equal to 3moles
NADH is an energy carrier which delivers high energy electrons to the electron transport chain where they will eventually power the production of 2 to 3 ATP molecules.
FADH is another energy carrier that carries high energy electrons to the ETC, where they will drive the production of 1 to 2 ATP molecules.
Electron transport chain produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria. This stage converts the NADH into ATP.
NADH = 3ATP FADH2 = 2ATP
