Question 6

Many drugs exert their therapeutic effects by inhibiting specific enzymes. If a drug acts as a competitive inhibitor, what effect would increasing the substrate concentration typically have on the enzyme's activity in the presence of the drug?

Accepted Answer

C. Overcome the inhibition — Competitive inhibitors bind to the enzyme's active site, competing with the natural substrate. Increasing the substrate concentration can outcompete the inhibitor for the active site, thereby overcoming the inhibition and allowing the enzyme to approach its maximal velocity (Vmax). Competitive inhibition increases the apparent Km but does not alter Vmax.

Answer

D. Have no effect on the enzyme activity
