[[Creatine]], an organic compound found in animals, provides a way for ATP to be utilized in the muscle. The phosphorylation of creatine allows for the storage of readily available phosphate that can be supplied to the muscles.<ref>{{Cite journal |last1=Sahlin |first1=Kent |last2=Harris |first2=Roger C. |date=2011-05-01 |title=The creatine kinase reaction: a simple reaction with functional complexity |url=https://doi.org/10.1007/s00726-011-0856-8 |journal=Amino Acids |language=en |volume=40 |issue=5 |pages=1363–1367 |doi=10.1007/s00726-011-0856-8 |pmid=21394603 |s2cid=12877062 |issn=1438-2199}}</ref>

creatine + ATP ⇌ phosphocreatine + ADP + H<sup>+</sup>

The reaction is reversible as well, allowing cellular ATP levels to be maintained during anoxic conditions.<ref>{{Citation |last1=Wang |first1=Y. |title=HYPOXIA {{!}} Anaerobic Metabolism in Fish |date=2011-01-01 |url=https://www.sciencedirect.com/science/article/pii/B9780123745538001544 |encyclopedia=Encyclopedia of Fish Physiology |pages=1757–1763 |editor-last=Farrell |editor-first=Anthony P. |access-date=2023-04-18 |place=San Diego |publisher=Academic Press |language=en |doi=10.1016/b978-0-12-374553-8.00154-4 |isbn=978-0-08-092323-9 |last2=Richards |first2=J.
