Triclosan is a broad-spectrum antibacterial agent used in many household products. It is structurally similar to polychlorobiphenylol, a substrate that binds to the active site of the enzyme sulfotransferase. Based on these facts, you can conclude that triclosan most likely:
A. lowers the activation energy of chemical reactions.
B. functions as an enzyme when sulfotransferase is absent.
C. is a competitive inhibitor.
D. acts as a noncompetitive inhibitor.
