The given table shows the percentage of product formation in an enzyme-catalysed reaction at different temperatures. Which percentage of product formation shows optimum temperature?"
Correct answer: D. IV
- A. I
- B. II
- C. III
- D. IV
Explanation
The temperature at which enzyme shows maximum activity is called optimum temperature.Enzyme activity increases up to optimum temperature. So 35 degree Celsius is the optimum temperature here. So D is correct. All others form reduced products so they are incorrect.

About Factors Affecting Enzyme Action
Enzyme activity changes with temperature, pH, substrate concentration and enzyme concentration because these factors affect molecular collisions and the active site. Questions also examine optimum conditions, denaturation and inhibition, while distinguishing a fall in activity caused by unsuitable conditions from permanent enzyme damage.
