What is the source of energy for the generation of ATP from ADP in oxidative phosphorylation?

Question

Quizplus · Accepted Answer

During oxidative phosphorylation, the source of the generation of ATP (adenosine triphosphate) is the movement of hydrogen ions (protons) from the intermembrane space of the mitochondria into the mitochondrial matrix through the complexes of the electron transport chain. This creates a gradient of protons with a higher concentration in the intermembrane space and a lower concentration in the matrix. This gradient drives the synthesis of ATP by the enzyme ATP synthase, which uses the energy from the movement of the protons to join ADP (adenosine diphosphate) and phosphate groups to form ATP. Therefore, the movement of hydrogen ions into the mitochondrial matrix is the source of the generation of ATP.
