Each NADH that enters the electron transport system gives rise to _____ ATP.

Question

Quizplus · Accepted Answer

Each NADH molecule that enters the electron transport chain results in the production of approximately 3 molecules of ATP. This is due to the fact that the electron transport chain generates a proton gradient across the inner mitochondrial membrane, which is used to drive ATP synthesis via the enzyme ATP synthase. In contrast, each FADH2 molecule that enters the electron transport chain results in the production of approximately 2 molecules of ATP. Therefore, the total number of ATP molecules generated by the electron transport chain depends on the number of NADH and FADH2 molecules produced during the breakdown of glucose and other fuels. In aerobic respiration, the maximum yield of ATP from the breakdown of glucose is 36-38 molecules, depending on the source of information.
