Question

Quizplus · Accepted Answer

Each NADH molecule fed into the electron transport chain produces enough energy to generate 3 ATP molecules. This is due to the number of protons that are pumped across the mitochondrial inner membrane by the electron transport chain, which generates the potential gradient used to drive ATP synthesis by ATP synthase. In contrast, each FADH2 molecule only produces enough energy to generate 2 ATP molecules.
