Creatine's main benefit is its ability to aid in the production of energy. When ATP (adenosine triphosphate) loses one of its phosphate molecules and becomes ADP (adenosine diphosphate), it must be converted back to ATP in order for the molecule to be able to produce energy again. The creatine in our body is mostly stored as creatine phosphate (known as phosphocreatine), and it will donate its phosphate to the ADP which renews the ATP molecule and it can now produce energy.
Creatine phosphate, oxidative phosphorylation, and glycolysis.
Creatine phosphate exist in muscle and brain cells.
The level of muscle that creatine-phosphate powers is striated or skeletal muscles.

Creatine Phosphate cannot directly supply energy to a cell, instead, it stores energy released from mitochondria. Whenever sufficient ATP is present, an enzyme in the mitochondria (creatine phosphokinase) promotes the synthesis of creating phosphate, which stores excess energy in its phosphate bond.
The enzyme creatine kinase catalyzes the reaction that creates creatine phosphate. This reaction involves transferring a phosphate group from ATP to creatine, forming creatine phosphate and ADP. Creatine phosphate serves as a short-term energy reservoir in muscle cells.
Creatine phosphate is regenerated during rest or low-intensity exercise when ATP levels are sufficient. During these periods, creatine kinase catalyzes the transfer of a phosphate group from ATP to creatine to regenerate creatine phosphate.
Creatine phosphate and ATP are both sources of energy for the muscles. Creatine phosphate is found in vertebrate muscle, while ATP can be found anywhere within the cell.
Creatine phosphate + ADP_______> creatine + ATP This is catalyzed by the enzyme creatine kinase.
Creatine phosphate functions in the muscle cell by storing energy that will be transferred to ADP to resynthesize ATP.
Creatine phosphate serves as a quick and immediate energy source for the regeneration of ATP during short, intense bursts of physical activity, such as weightlifting or sprinting. It helps to maintain energy levels in muscle cells, allowing for increased performance and power output.
The creatine phosphate system occurs in the cytoplasm of muscle cells. It provides a rapid source of ATP for muscle contractions during short bursts of high-intensity exercise.
