Question

13 which of the following is the optimal temperature for the bacterias enzyme activity? a 20°c b 70°c c 40°c d 90°c

Explanation:

Most bacterial enzymes have an optimal activity around 40°C. Temperatures too high (like 70°C and 90°C) can denature enzymes, and 20°C is generally on the lower - end for optimal activity for many bacteria.

Answer:

B. 40°C
