Competitive inhibition is a form of enzyme inhibition where binding of the inhibitor to the active site on the enzyme prevents binding of the substrate and vice versa. Most competitive inhibitors function by binding reversibly to the active site of the enzyme.
1 In mixed inhibition, the inhibitor can bind to the enzyme at the same time as the enzyme's substrate. 2  However, the binding of the inhibitor affects the binding of the substrate, and vice versa. 3  This type of inhibition can be reduced, but not overcome by increasing concentrations of substrate.n enzyme inhibitor is a molecule that binds to an enzyme and decreases its activity. Since blocking an enzyme's activity can kill a pathogen or correct a metabolic imbalance, many drugs are enzyme inhibitors.
