In oxidative phosphorylation,energy for the synthesis of ATP is directly obtained from

Question

Quizplus · Accepted Answer

During oxidative phosphorylation, energy is obtained from the movement of hydrogen ions through channels in the inner mitochondrial membrane, which creates a proton gradient. This proton gradient is then used to drive the synthesis of ATP through the action of ATP synthase. The oxygen molecules are used as the final electron acceptor in the electron transport chain, but they do not provide direct energy for ATP synthesis. Glucose and acetyl-CoA are both sources of energy, but they are broken down in earlier steps of cellular respiration, and their energy is used to create the proton gradient used in oxidative phosphorylation. Water is a product of cellular respiration, but it does not provide energy for ATP synthesis.
