* * *

(ATP) a nucleotide, the 5′-triphosphate of adenosine, involved in energy metabolism and required for RNA synthesis; it occurs in all cells and is used to store energy in the form of high-energy phosphate bonds. The free energy derived from hydrolysis of ATP is used to drive metabolic reactions including the synthesis of nucleic acids and proteins, to move molecules against concentration gradients (active transport), and to produce mechanical motion (contraction of microfibrils and microtubules).
