In the induced-fit model, the enzyme's active site changes shape upon substrate binding to form an enzyme-substrate complex, which can distort substrate bonds and promote the reaction.
The induced-fit model describes how an enzyme's active site changes shape as the substrate binds, forming an enzyme-substrate complex and potentially stressing bonds in the substrate to facilitate the reaction.
