In the electron transport chain, one NADH molecule supplies the energy to phosphorylate ___ ADP molecules, and one FADH₂ supplies the energy to phosphorylate ___ ADP molecules.

Question

Quizplus · Accepted Answer

One NADH molecule supplies the energy to phosphorylate approximately 2.5 ADP molecules, while one FADH2 molecule supplies the energy to phosphorylate approximately 1.5 ADP molecules in the electron transport chain. This difference is due to the point at which NADH and FADH2 enter the electron transport chain, with NADH contributing its electrons at an earlier stage than FADH2, thus providing more energy for ATP synthesis.
