WebDec 30, 2024 · However, the pyrophosphate released is quickly hydrolyzed by inorganic pyrophosphatase, a ubiquitous cytosolic enzyme, in a highly exergonic reaction. This pyrophosphate hydrolysis is a mechanism utilized in many biosynthetic pathways to provide energy for otherwise endergonic reactions. WebHydrolysis is a chemical reaction during which polymers (large molecules) break down into monomers (small molecules).. During hydrolysis, covalent bonds between monomers break, which allows for the breaking down of polymers. Bonds are broken down using water.Hydro literally means 'water', and - lysis stands for 'to unbind'.
