Which one of the following statements is incorrect

Options

A. In competitive inhibition, the inhibitor molecule is not chemically changed by the enzyme
B. The competitive inhibitor does not affect the rate of breakdown of the enzyme-substrate complex
C. The presence of the competitive inhibitor decreases the `K_m` of the enzyme for the substrate
D. A competitive inhibitor reacts reversibly with the enzyme to form an enzyme-inhibitor complex

Answer

C

Explanation

Competitive inhibitors can only bind to E and not to `E_m`. They increase Km by interfering with binding to the substrate.
