Competitive inhibition is characterized by all the following, except: (A) Inhibitor is a structural analogue of the substrate, (B) Inhibitor binds to the active site, (C) Increases Km value, (D) Irreversible
Answer is D. A competitive inhibitor has no effect on Vmax but raises K'm, the apparent Km for the substrate. AND ITS REVERSIBLE. Inhibition is overcome by increasing the concentrations of the substrate.
