WebMar 7, 2008 · When the cell has excess energy, it stores this energy by forming ATP from ADP and phosphate. ATP is required for the biochemical reactions involved in any muscle contraction. 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. Because ATP is so important, … WebWhen energy is released, AT P loses one of its phosphate groups and turns to ADP (ADENOSINE DI-PHOSPHATE). ADP is present in cells and has two phosphate groups firmly attached. The energy from respiration is used to form another phosphate group to each molecule to form AT P. greek mythology books for the classroom
