Binding change hypothesis
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. WebAccording to this “binding change” hypothesis, the synthesis of ATP proceeds in a cycle. First, ADP and phosphate are bound to the loose binding site, L. A conformational …
