C)an allosteric inhibitor
D)both an irreversible and a reversible inhibitor

Question

Quizplus · Accepted Answer

Irreversible inhibitors permanently alter the enzyme they inhibit by covalently binding to amino acid residues of the enzyme, which changes its shape and activity. Reversible inhibitors, on the other hand, bind non-covalently to the enzyme and do not permanently alter its structure. Allosteric inhibitors are a type of reversible inhibitor that binds to a specific site on the enzyme, called the allosteric site, and changes its shape, which affects its activity. Therefore, the correct answer is A) an irreversible inhibitor.
