|
|
|
The inhibitor molecule binds to side chains of the polypeptide chains of the enzyme so it cannot interact with the substrate
|
|
|
The inhibitor molecule competes with the substrate to bind to the active site of the enzyme
|
|
|
The inhibitor molecule binds to site distinct from the active site but causes the conformational change of the 3d structure of the active site
|
|
|
None of the above
|
Detailed explanation-1: -Reversible Inhibition. A reversible inhibitor inactivates an enzyme through noncovalent, more easily reversed, interactions. Unlike an irreversible inhibitor, a reversible inhibitor can dissociate from the enzyme. Reversible inhibitors include competitive inhibitors and noncompetitive inhibitors.
Detailed explanation-2: -The competitive inhibitor binds to the active site and prevents the substrate from binding there. The noncompetitive inhibitor binds to a different site on the enzyme; it doesn’t block substrate binding, but it causes other changes in the enzyme so that it can no longer catalyze the reaction efficiently.
Detailed explanation-3: -Irreversible inhibitors bind to the enzyme’s binding site then undergo a chemical reaction to form a covalent enzyme-inhibitor complex (EI*).
