MUSCLE PHYSIOLOGY

Detailed explanation-1: -Creatine phosphate is a molecule that can store energy in its phosphate bonds. In a resting muscle, excess ATP transfers its energy to creatine, producing ADP and creatine phosphate. This acts as an energy reserve that can be used to quickly create more ATP.

Detailed explanation-2: -Creatine may be delivered to the muscle, where it may combine readily with phosphate to form creatine phosphate, a high-energy phosphagen in the ATP-CP system, and is stored. The ATP-CP energy system is important for rapid energy production, such as in speed and power events.

Detailed explanation-3: -Creatine phosphate or phosphocreatine, is a phosphorylated creatine molecule that serves as a rapid release reserve of high-energy. It’s used in muscle cells to store energy for sprinting and explosive exercise.

Detailed explanation-4: -Creatine is transported into the muscle cell by a specific transporter, resulting in increased intracellular creatine and PCr. The PCr is capable of acting as an energy buffer, protecting the adenosine triphosphate (ATP) concentration. Maintaining muscle nucleotides therefore enhances exercise performance and recovery.
