WebAs the ATP produced by creatine phosphate is depleted, muscles turn to glycolysis as an ATP source. Glycolysis is an anaerobic (non-oxygen-dependent) process that breaks down glucose (sugar) to produce ATP; however, glycolysis cannot generate ATP as quickly as creatine phosphate. WebATP is broken down and rebuilt many times to make energy available for muscular movement. It is resynthesised almost as quickly as it is broken down. It is summarised as follows: - chemically, ATP is an adenosine nucleotide bound to three phosphates - when a cell needs energy, it breaks the bond between the second and third phosphate groups.
