Principles of Chemical Thermodynamics and Kinetics
... The induced fit model is used to explain the mechanism of action for enzyme function seen in Figure 10-2. Once a substrate binds loosely to the active site of an enzyme, a conformational change in shape occurs to cause tight binding between the enzyme and the substrate. This tight binding allows the ...
