Question

If an enzyme inhibitor binds at a site other than the active site of the enzyme, the nature of the inhibitor is described as

A. competitive
B. non-competitive
C. reversible
D. All of the above

Answer 1

B. non-competitive

Step-by-step explanation:

As opposed as competitive inhibition, the non-competitive one does not bind with the active region of the enzyme. However, it does reduce the efficiency of the reaction because it changes the protein structure, making it unavailable for substrate.

Reversibility is related to the possibility of the reaction to be undone. If the bond is covalent, the enzyme will not return to its active state, so that would be a non-reversible bind.
