ATP (Adenosine triphosphate). 1  It is the major energy currency of the cell, providing the energy for most of the energy-consuming activities of the cell. 2  It is one of the monomers used in the synthesis of RNA and, after conversion to deoxyATP (dATP), DNA.3  It regulates many biochemical pathways.

Adenosine triphosphate is a nucleoside triphosphate used in cells as a coenzyme. It is used to transport chemical energy within cells for metabolism. Another name for ATP is Adenosine triphosphate. ATP is produced by almost all living things in organelles called mitochondria found in cells. It is not energy itself, but rather temporarily stores energy in its' bonds. When the third phosphate bond is broken, energy is released. This creates ADP which has one less phosphate attached to the group.
