Enzyme inhibition 2 It is the decline the due to bo- binding Ae enzyme activity of inhibitor to the Ae enzyme: (decrease in Enzyme activity due to the binding) of inhibitors. Reversible inhibitors → Inhibitors bind to enzymes by weak, easily dissociable non-covalent bonds. When inhibi kor restored is removed enzyme activity Pally. 3 types of Reversible inhibitors.
