WebJun 8, 2024 · This dynamic binding maximizes the enzyme’s ability to catalyze its reaction. Figure 6.10. 1: Induced Fit: 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 rate of the reaction. WebOne model of enzyme mechanism is called the induced fit model. This model proposes that the binding of the reactant, or substrate, to the enzyme active site results in a conformational change to the enzyme. This change stabilizes the transition state complex, and thus lowers the activation energy. Ways That Enzymes Catalyze Reactions hill slough wildlife area https://lancelotsmith.com
