WebWhen the inhibitor binds to the allosteric site, it causes a conformational shape change, preventing the enzyme's substrates from attaching to it. Thus preventing the breakdown or formation of a molecule. Irreversible inhibitors have two forms; irreversible competitive inhibitors or irreversible noncompetitive inhibitors. WebSep 15, 2024 · Feedback inhibition is a normal biochemical process that makes use of noncompetitive inhibitors to control some enzymatic activity. In this process, the final product inhibits the enzyme that catalyzes the first step in a series of reactions. Feedback inhibition is used to regulate the synthesis of many amino acids.
