Consider the following graph for the rate of an enzyme catalyzed reaction.  What is the approximate optimum temperature for carrying out this reaction?
A) 20°C 
B) 25°C 
C) 35°C 
D) 45°C

Quizplus · Accepted Answer

The graph shows that the reaction rate increases steadily from 0°C to approximately 35°C, where it reaches a plateau. The plateau suggests that the enzyme has reached its maximum activity and any further increase in temperature will denature the enzyme, leading to a decrease in the reaction rate. Therefore, the approximate optimum temperature for carrying out this reaction is around 35°C.
