Each NADH that enters the electron transport system gives rise to a maximum of ________ ATP.

Question

Quizplus · Accepted Answer

Each NADH can generate up to 3 ATP molecules during oxidative phosphorylation, whereas each FADH2 can produce up to 2 ATP molecules. Therefore, the total number of ATP molecules produced from the electron transport chain depends on the number of NADH and FADH2 molecules that are oxidized. In general, it is estimated that each NADH molecule produces 2.5 to 3 ATP molecules, and each FADH2 molecule produces 1.5 to 2 ATP molecules. The maximum yield of ATP from the complete oxidation of glucose is therefore 36 to 38 ATP molecules, depending on the type of tissue or cell and other factors.
