In term of enzyme actions, 'maximum temperature' refers to a temperature at which:
Correct answer: A. Enzymes start to denature
- A. Enzymes start to denature
- B. Enzymes start to re-nature
- C. Enzymes work best
- D. Enzymes are reactivated
Explanation
The term "maximum temperature" means the point at which enzymes start to denature (Option A). Denaturation is when enzymes lose their shape and stop working due to excessive heat.

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.
