Detailed explanation-1: -The phosphagen system (also called the ATP-CP system) is the quickest way to resynthesize ATP (Robergs & Roberts 1997). Creatine phosphate (CP), which is stored in skeletal muscles, donates a phosphate to ADP to produce ATP: ADP + CP = ATP + C.
Detailed explanation-2: -Answer and Explanation: In order to regenerate ATP in muscle cells, creatine phosphate (CP) will donate its phosphate group to ADP. This occurs through the action of the enzyme creatine phosphokinase, and will yield one ATP molecule. Creatine phosphokinase will then be turned into creatine.
Detailed explanation-3: -Direct Phosphorylation uses the Creatine Phosphate stored in muscles to reattach a phosphate group to the ADP left behind after ATP gets used for energy. This storage supply lasts less than 15 seconds and only creates 1 new ATP per molecule.
Detailed explanation-4: -During times of acute energy need, the creatine kinase (EC2. 7.3. 2) uses creatine phosphate for the ultrarapid phosphorylation of ADP to ATP.
