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.
 2. Competitive and Noncompetitive  inhibition-Limits the enzyme activity. This occurs when a molecule  binds to an enzyme, either on the active site or allosteric site,  and decreases its activity.  3. Allosteric Regulation-Causes a  different shape in the enzyme.May either inhibit or stimulate an  enzymes activity.2. Competitive and Noncompetitive  inhibition-Limits the enzyme activity.
