Adenosine triphosphate (ATP) is the primary energy molecule which can be used to perform cellular functions.
ATP is a very important carrier of energy for the cell as energy is released when one of the phosphate groups is removed.
Mitochondria help in oxidative phosphorylation and generation of adenosine triphosphate.
The most important form of “energy currency” in living systems is the bond energy in a chemical called adenosine triphosphate (ATP).
