Which enzyme is responsible for catalyzing the hydrolysis of ATP?

ATPase is the enzyme responsible for catalyzing the hydrolysis of ATP (adenosine triphosphate). This process involves the breakdown of ATP into ADP (adenosine diphosphate) and an inorganic phosphate, releasing energy that is essential for various cellular functions. The activity of ATPase is crucial in energy metabolism, as it provides the energy required for many biochemical reactions and processes within the cell.

ATPases can be found in various forms, such as F-type ATP synthases and V-type ATPases, but their fundamental role remains the same: facilitating the conversion of ATP to ADP and freeing energy that cells can utilize for work. Understanding the action of ATPase is key to grasping how cells manage energy and perform essential functions.
