A drug that binds to the active site of the enzyme and prevents substrate binding is a competitive inhibitor. Competitive inhibitors bind to the active site of the enzyme and compete with the substrate for binding. Noncompetitive inhibitors bind to a different site on the enzyme and change its shape, making it unable to bind to the substrate. Allosteric inhibitors and activators also bind to a different site on the enzyme and regulate its activity.
