WebFeb 11, 2016 · ATP is an energy carrying molecule that consists of adenosine and three phosphate groups. To prevent the energy of ATP from dissipating and being wasted as heat, the energy is only released when it is hydrolyzed (split under the use of water) by enzymes called ATPases. All of our cells contain these enzymes, and especially our muscle fibers. WebThe phosphagen system consists of the ATP store and the phosphocreatine (PC) (also called creatine phosphate) store (see upper section of Fig. 8-1 ). The ATP store in the body is small and is sufficient to allow maximal effort for about 1 to 2 seconds, but there are ways of providing more ATP to replace that being used during metabolism.

WebJun 11, 2024 · Phosphocreatine ATP has to be made by adding a phosphate group (P i) to ADP. In the ATP-phosphocreatine system, the phosphate group comes from phosphocreatine stored inside the muscle fibre cells. … WebThis series of reactions is the basis of the ATP-PC system. In summary, ATP synthesises to ADP and resynthesises to ATP with the help of PC molecules and Creatine Kinase. These reaction take place very quickly inside the muscles, and because PC is stored in the muscles it is the first energy system used during high intensity physical activity. cit-us-aw1694-50a
