nmdcat.online July 11, 2026

In enzyme kinetics, the reaction reaches a maximum rate when

A. Every enzyme molecule has an occupied active site

✓

B. Product concentration becomes zero

C. Temperature reaches freezing point

D. The enzyme becomes denatured

📝 Explanation

At substrate saturation, all available active sites are occupied, so adding more substrate cannot further increase the reaction rate.

📖 Additional Information

Every enzyme molecule has an occupied active site
Product concentration becomes zero
Temperature reaches freezing point
The enzyme becomes denatured

At substrate saturation, all available active sites are occupied, so adding more substrate cannot further increase the reaction rate.
