a source of energy

ATP is a high-energy molecule composed of a purine base (adenine), a five-carbon sugar (ribose), and three phosphate groups. It is primarily used as a source of energy in living organisms.

ATP supplies energy to every endergonic reaction that occurs in the body. For example, the energy from ATP can be used by the organism to obtain, transform, and transport materials, and to eliminate wastes.
