Adenosine triphosphate (ATP) is used as a source of free energy to drive reactions in the cell. Hydrolysis of ATP is slow in the absence of catalysis. Enzymes couple ATP hydrolysis to reactions whose equilibrium lies on the side of the reactants. Enzymes that utilize ATP hydrolysis including motor proteins like myosin, ion pumps, and many biosynthetic enzymes. ATP also is the source of phosphate for many phosphorylation reactions. In eukaryotes, ATP is synthesized mainly in mitochondria (and chloroplasts in plants).
