Trifosfato de adenosina CAS:56-65-5

Trifosfato de adenosina disódico(ATP) are used as the main energy source for metabolic functions. They are consumed by energy-requiring (endothermic) processes and produced by energy-releasing (exothermic) processes in the cell. It does this by giving either losing or gaining a phosphate group.

Energy is transferred as a matter of how many phosphate group the molecules have. ATP energizes the endothermic process thus becoming ADP. While ADP can take up energy from an exothermic process and gain a phosphate (phosphorylated) to become ATP.
