Chemiosmosis:

Quizplus · Accepted Answer

Chemiosmosis involves the generation of ATP by using the energy stored in an electrochemical gradient of protons (H+) across a membrane. During cellular respiration, the electron transport chain pumps protons from the mitochondrial matrix to the intermembrane space, creating a gradient. The movement of protons back to the mitochondrial matrix through ATP synthase powers the creation of ATP from ADP and inorganic phosphate. This is the basis for the ATP synthesis in oxidative phosphorylation.
