Document Summary
Power perspective: phosphocreatine system will be active for a short duration (atp is being broken down). This system is used when there is a maximum effort given for a short duration that is very explosive. The following is a diagram of the structural make-up of an atp molecule, showing the high-energy phosphate bonds and energy release. Myosin atpase converts atp to adp + p + energy. Recovery runs the opposite direction and happens during aerobic metabolism. This is a diagram showing how atp levels are maintained from the energy stored in pcr replenishment. The breakdown of pcr energy atp (during exercise) Recovery: forming atp aerobically (elevated oxygen uptake: we use a little bit of energy to bind the cleaved phosphate with the diphosphate giving us more atp, the energy will be used to regenerate pcr. Creative-kinase: reversible reactions that can go both ways (can break down pcr and form pcr). Pcr adp + pi atp.
