How is atp synthase involved in making energy available to the cell?

Best   ATP synthase makes ATP. found in the inner mitochondrial membrane, it uses the energy of the proton electrochemical gradient produced by the electron transport chain to make atp from adp and inorganic phosphate. the enzyme itself has a passage for protons, and a head which turns. The head has 3 idential components. passing 10 protons through will turn the head once. ADP and phosphate can bind to one of the 3 components and the turning will cause the component to essentially sequeeze the ADP and phosphate together to make ATP.
