Adenosine triphosphate (ATP) is a molecule that functions as the primary energy currency of the cell. It stores energy that cells can use to perform various metabolic processes, such as biosynthesis, active transport, and muscle contraction.
ATP is composed of an adenosine molecule and three phosphate groups. When ATP is broken down, energy is released as the bonds between the phosphate groups are hydrolyzed. The energy released can then be used to drive other cellular processes. The cycle of ATP synthesis and degradation serves as a central source of energy for many cellular functions.
