Web1. Allosteric competitive: i: enzyme + inhibitor -/-> no reaction because enzyme changes conformation. ii: enzyme + substrate -> reaction takes place until the enzyme gets changed when an inhibitor successfully competed (1.i:) against the binding of a substrate and is attached to the enzyme. 2. Noncompetitive: WebCompetitive inhibitors are one of three sub-categories of reversible enzyme inhibitors. The intended substrate molecules may be blocked from access to the enzyme active site by the imitating competitive inhibitor. This process is possible as the size and shape of the competitive inhibitor is relatively similar to that of the substrate [1]. townsend montana newspaper
