Detailed explanation-1: -ATP is replenished by using phosphocreatine to convert adenosine diphosphate (ADP) into ATP in the mitochondria of cells within the muscle tissue. ATP is therefore produced from glucose (carbohydrates) through the glycolytic pathway.
Detailed explanation-2: -Function. Phosphocreatine can anaerobically donate a phosphate group to ADP to form ATP during the first five to eight seconds of a maximal muscular effort. Conversely, excess ATP can be used during a period of low effort to convert creatine back to phosphocreatine.
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.
