Which factor does NOT affect enzyme activity?
Correct answer: D. Color of the solution
- A. Temperature
- B. pH
- C. Substrate concentration
- D. Color of the solution
Explanation
Enzyme activity is affected by temperature, pH, substrate concentration, and presence of inhibitors/activators, but not by color.

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.
