Muscle contraction happens only when the energy molecule called adenosine triphosphate (ATP) is present. ATP has three phosphate groups that it can give away, releasing energy each time.
Adenosine triphosphate (ATP) is the biochemical way to store and use energy. F or your muscles -- in fact, for every cell in your body -- the source of energy that keeps everything going is called ATP. Adenosine triphosphate (ATP) is the biochemical way to store and use energy. When the cell has excess energy, it stores this energy by forming ATP from ADP and phosphate. 2  ATP is required for the biochemical reactions involved in any muscle contraction. 3  As the work of the muscle increases, more and more ATP gets consumed and must be replaced in order for the muscle to keep moving.
