Competitive enzyme inhibition will cause_____________?
Correct answer: D. Increase of km and Unchanged of Vmax
- A. Decrease of km and increase of Vmax
- B. increase of km and increase of Vmax
- C. Decrease of km and decrease of Vmax
- D. Increase of km and Unchanged of Vmax
Explanation
A competitive inhibitor competes at the active site, so a higher substrate concentration is needed to reach half-maximal velocity, increasing apparent Km. It can be overcome by excess substrate, leaving Vmax unchanged.
