Question
In an enzymatic reaction, a non-competitive inhibitor:
| A. |
diminishes KM |
| B. |
diminishes Vmax |
| C. |
diminishes KM and Vmax |
| D. |
does not affect Vmax |
Show Answer

Correct Answer � B Explanation |
 |
Answer- B
Noncompetitive inhibition lowers the Vmax. Thus, the enzyme simply cannot catalyze the reaction with the same efficiency as the uninhibited enzyme. Note that noncompetitive inhibition cannot be overcome by raising the substrate concentration like competitive inhibition can
