Biology for IGCSE & O level - Enzymes (Section 1 - No. 6)
What is the effect of increasing substrate concentration on the rate of an enzyme-catalyzed reaction, assuming other factors are constant?
The rate decreases.
The rate remains constant.
The rate increases until saturation.
The enzyme denatures.
Explanation
Increasing substrate concentration increases the rate of reaction until all enzyme active sites are occupied.
