How does a noncompetitive inhibitor affect an enzyme?
Answer: C
Correct answer: Lowers the maximum rate of the enzymatic reaction
A noncompetitive inhibitor binds at a separate site and disables whatever enzyme molecules it occupies, whatever the substrate concentration. In effect it removes enzyme from the pool, so \(V_{max}\) falls while \(K_m\) stays the same - the molecules still working have the same affinity as before.
