If an enzyme in solution is saturated with substrate, the most effective way to obtain a faster yield of products is to ________.
A) add more of the enzyme
B) heat the solution to 90°C
C) add more substrate
D) add a noncompetitive inhibitor

Question

Quizplus · Accepted Answer

Adding more of the enzyme increases the number of active sites available for the substrate, thus increasing the rate of reaction. When the enzyme is already saturated with substrate, adding more substrate or a noncompetitive inhibitor won't increase the rate of product formation. Heating the solution to 90°C is likely to denature the enzyme, reducing its activity.
