The body has three ways of producing ATP: from creatine phosphate, anaerobic cellular respiration and aerobic cellular respiration. (Jenkins et all, 2007) At rest, the muscle fiber produce more ATP than is required by the body. This excess ATP is used to synthesize creatine phosphate – an energy rich molecule found only in the muscle fiber. Creatine is a small molecule that muscle cells assemble from fragments of amino acids. (Martini, 2008)  The enzyme creatine kinase catalyzes muscles fibers to break down excess ATP and transfer a phosphate group to creatine, forming creatine phosphate and ADP. (Jenkins et all, 2007) (more…)
