WebThe induced fit model states that the active site of an enzyme will undergo a conformational change when binding a substrate, to improve the fit. The induced fit model accounts for the broad specificity of enzymes as the active site is not rigid, but can undergo a conformational change to better fit the substrate binding. WebFigure 6.16 According to the induced-fit model, both enzyme and substrate undergo dynamic conformational changes upon binding. The enzyme contorts the substrate into its transition state, thereby increasing the reaction's rate. …

WebNov 19, 2024 · The induced fit model describes the formation of the E-S complex as a result of the interaction between the substrate and a flexible active site. The substrate produces changes in the conformation on the enzyme aligning properly the groups in the enzyme. It allows better binding and catalytic effects. WebJan 28, 2024 · A substrate binds to a specific region on an enzyme known as the active site, where the substrate can be converted to product.
