"WebCompetitive Inhibitors. In competitive inhibition, a molecule similar to the substrate but unable to be acted on by the enzyme competes with the substrate for the active site.Because of the presence of the inhibitor, fewer active sites are available to act on the substrate.

WebCompetitive inhibitors impair reaction progress by binding to an enzyme, often at the active site, and preventing the real substrate from binding. At any given time, only the competitive inhibitor or the substrate can be bound to the enzyme (not both). That is, the inhibitor and substrate compete for the enzyme. Competitive inhibition acts by ... WebGeneral representation of uncompetitive inhibition. Uncompetitive inhibition, also known as anti-competitive inhibition, takes place when an enzyme inhibitor binds only to the complex formed between the enzyme and the substrate (the E-S complex). Uncompetitive inhibition typically occurs in reactions with two or more substrates or products.
