Glossary Term

Adenosine Triphophatase (ATPase)

Adenosine triphosphatase (ATPase) is an enzyme that catalyzes the breakdown of adenosine triphosphate (ATP) to adenosine diphosphate (ADP), releasing energy for various processes like muscular contraction. This dephosphorylation reaction is crucial for the proper functioning of cells and organisms.

Adenosine triphosphatase (ATPase): is the enzyme responsible for catalyzing (initiating and accelerating) the decomposition of ATP to ADP.

  • This dephosphorylation (breakdown) reaction releases energy for processes like muscular contraction.
