Ritonavir is an anti-viral drug that mimics the natural substrate for a key viral protease enzyme. As a competitive inhibitor, ritonavir:
decreases the rate of reaction because it decreases the availability of ATP to catalyze the reaction.
increases the rate of reaction by altering the tertiary structure of the enzyme.
decreases the rate of reaction by binding to the enzyme and altering the structure of its active site.
decreases the rate of reaction by binding to the active site.
I always thought competitive inhibition had no effect on the Vmax?? But all answer choices talk about a change in the reaction rate?
