ATPase - Wikipedia
WEBATPase (also called F 0 F 1-ATP Synthase) is a charge-transferring complex that catalyzes ATP to perform ATP synthesis by moving ions through the membrane. [12]

WEBThe term ATPase applies to the activity of any enzyme’s ability to decompose ATP, including metabolic enzymes involved in anabolic processes that need energy, as well as enzymes promoting transport across membrane. In the former case, the enzyme decomposes ATP using the energy liberated to do work; for instance, enzymes such as …
