The rate of product formation by an enzyme-catalyzed reaction would be increased by
A) adding more substrate molecules.
B) adding more product molecules.
C) reducing the number of enzymes.
D) reducing the number of substrate molecules.

Question

Quizplus · Accepted Answer

The rate of product formation in an enzyme-catalyzed reaction is directly proportional to the concentration of substrate molecules. Adding more substrate molecules will increase the probability of enzyme-substrate collision, leading to more enzyme-substrate complexes and increased product formation. Adding more product molecules or reducing the number of enzymes or substrate molecules will not affect the rate of reaction.
