Complex molecular machines like ATP synthase are often used in multiple different places within a cell. Cells may also use closely related forms, for example, the V-ATPases, to perform other tasks such as using ATP to pump protons into the lysosome. ATP synthase itself can use a chemical gradient to create ATP or be used as an ATP-driven proton pump.
