Adenosine

Triphosphate Adenosine Triphosphate (ATP) is a major source of energy in living cells. It is found in every living organism and is the main source of energy for biochemical reactions, playing a crucial role in metabolism, cellular respiration and ion transport. ATP is essential for muscle contraction and nerve impulses, making it essential for many physiological processes. It is also used as an energy currency in many biochemical pathways and is involved in the regulation of cell growth, differentiation and death. ATP is therefore an essential molecule for life.
