The addition of a competitive inhibitor slows down a particular reaction. What could be done to increase the rate of the reaction, even in the presence of the inhibitor?
A) Add more inhibitor.
B) Add more substrate.
C) Lower the temperature of the reaction.
D) Allow the reaction to reach equilibrium.
E) Add a coenzyme.

Adding more substrate can help overcome the effects of a competitive inhibitor by increasing the likelihood that the substrate rather than the inhibitor will bind to the active site of the enzyme, thus increasing the rate of the reaction. Competitive inhibitors compete with the substrate for binding to the active site, so increasing the concentration of the substrate can mitigate the impact of the inhibitor.
