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…)

The human body has always fascinated me and as I have sat in the Anatomy and Physiology class the last few months, I have had several ‘aha’ moments. The co-dependence of the different systems of the body to regulate and maintain the body’s proper functioning that extends to the cellular level of the body has completely amazed me.  It is hence not hard to conclude that no man-made system can be compared to the human body in its inherent complexity and perfection.
