Enzymes help reduce the activation energy of the complex molecules in the reaction. The following steps simplify how an enzyme works to speed up a reaction: Step 1: Each enzyme has an ‘active site’ which is where one of the substrate molecules can bind to. Thus, an enzyme- substrate complex is formed.Enzymes are essential for life, and understanding how they catalyze reactions in the body will book your understanding of how our bodies work.After an enzyme is done catalyzing a reaction, it releases its product (s). Figure 6.5. 2: 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.
