WebWhen an enzyme binds its substrate, an enzyme-substrate complex is formed. This complex lowers the activation energy of the reaction and promotes its rapid progression in one of many ways. On a basic level, enzymes promote chemical reactions that involve more than one substrate by bringing the substrates together in an optimal orientation. WebJan 28, 2024 · For an enzyme and substrate to bind they have to fit together physically. This is a cleft in the protein surface where the substrate binds. It has a shape that fits the substrate like a glove fits a hand or a lock fits a key. Only substrates with a particular molecular shape will have any chance to bind effectively.
