Glossary Term

Adenosine Triphosphate (ATP)

ATP is a molecule that provides energy for muscular contraction and human movement. It is composed of an adenine group, a ribose group, and three molecules of inorganic phosphates. Hydrolysis of ATP results in the cleaving of a phosphate group, releasing energy. Adenosine diphosphate and an inorganic phosphate group are also produced.

Adenosine triphosphate (ATP): The molecule that functions as a universal energy-transfer molecule, providing most of the energy associated with muscular contraction and human movement. ATP is composed of an adenine group, a ribose group, and three molecules of inorganic phosphates.

  • Energy is provided when hydrolysis results in the cleaving of a phophate group; resulting in adenosine diphosphate, an inorganigic phosphate group, and energy.
