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 non-competitive inhibition, the binding of the inhibitor to the enzyme reduces its activity but does not affect the binding of substrate. 2  As a result, the extent of inhibition depends only on the concentration of the inhibitor.n enzyme inhibitor is a molecule that binds to an enzyme and decreases its activity.
