Best Answer:
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.
