How does a substrate bind an enzyme

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. The ... WebMay 22, 2024 · How do the enzyme and substrate fit together? For an enzyme and substrate to bind they have to fit together physically. Each enzyme has a region on its surface called the active site (Figure 3). 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.
