None of the above

Detailed explanation-1: -Direct Phosphorylation of ADP by creatine phosphate. Aerobic Respiration. Anaerobic Glycolysis and lactic acid formation.
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: -The ATP–creatine phosphate system transfers a high-energy phosphate from creatine phosphate to adenosine diphosphate (ADP) to regenerate ATP. This anaerobic system can provide ATP for approximately 30 seconds for activities such as sprinting and weightlifting.
Detailed explanation-4: -Creatine phosphate is used because creatine phosphate and ADP are converted very quickly into ATP by creatine kinase. Glycolysis cannot generate ATP as quickly as creatine phosphate.
