- The following statements refer to enzyme inhibition. Match the statement to the one of the following descriptors to which it is best associated. Descriptors: competitive inhibition; non-competitive inhibition; un-competitive; covalent inhibition. 9a. Inhibition is not reversed even after the inhibitor (1) is removed from solution by dialysis or drug metabolism/excretion. 9b. Inhibitor and substrate reversibly compete for occupancy of a common binding site 9c. The inhibitor binds reversibly only to the preformed E.S (enzyme-substrate) complex forming an inactive E.S.I. 9d. The inhibitor binds reversibly and independently of substrate to an allosteric site producing E.I or a ternary E.S.I complex which can't form product. 9f. The relative amount of inhibition decreases as [S] (the concentration of substrate) increases and S better competes for occupancy of the active site.Identify the type of enzyme inhibition each of the following inhibitor characteristics is associated with: 1. An inhibitor that decreases enzyme activity by binding to a site on the enzyme other that the active site. 2.
