Biomolecules Question 147

Question: As temperature changes from $ 3^{o}C $ to $ 45^{o}C $ , the rate of enzyme activity will [MP PMT 1996]

Options:

A) Decrease and then increase

B) Increase and then decrease

C) Increase only

D) Decrease only

Show Answer

Answer:

Correct Answer: B

Solution:

If temperature increases from $ 3^{o}C $ to $ 45^{o}C $ , firstly it reaches to optimum condition and later temperature conditions are not optimum for enzyme activity.

Thus the rate of enzyme activity initially increases and then decreases.
