Feedback inhibition O The product of a series of reactions acts as an inhibitor for an earlier reaction. Hormones control the synthesis of enzymes. A regulator binds to the enzyme at a site other than the active site. This binding changes the shape of the enzyme and alters the catalytic ability of the enzyme. An inhibitor binds reversibly to the enzymesubstrate complex, blocking the binding of the second substrate to the active śite. The activity of an enzyme is influenced by the addition or removal of a group that is covalently bonded to the enzyme. An inhibitor forms covalent bonds to the active site, permanently blocking it.
