B) competitive inhibitor binding to the ES complex.
C) noncompetitive inhibitor binding to the ES complex.
D) Only A and C are correct.
E) Only A and B are correct.

Expert Solution

Step 1

The enzymes increase the rate of biochemical reactions and can be regulated by binding to inhibitors.

The inhibitors, based on their mode of action, can be classified as competitive, uncompetitive and noncompetitive inhibitor.

22.
An inhibitor was added to an enzyme and the expected rate of the reaction was not detected and the substrate was not utilized at all. This inhibitor is (choose one answer only): Is un-competitive, meaning the inhibitor binds to a site near the active site. Is competitive, meaning the inhibitor binds directly to the same active site as the subtrate. Is non-competitive, meaning the inhibitor binds to site other than the active site as the subtrate. Is irreversible, meaning the inhibitor binds covalently to the enzyme keeping the enzyme inactive permanently.
