The chemiosmotic theory explains that the energy for driving ATP formation in mitochondria comes from a proton concentration gradient.

Question

Quizplus · Accepted Answer

The chemiosmotic theory proposed by Peter Mitchell in 1961 states that the energy needed to drive ATP formation in mitochondria comes from a proton concentration gradient (or proton motive force) generated by the electron transport chain. This gradient is used by ATP synthase to convert ADP to ATP. Therefore, option A is correct.
