Biology for IGCSE & O level - Enzymes (Section 4 - No. 44)

What effect would increasing the concentration of substrate have on the rate of an enzyme-catalyzed reaction, assuming all other conditions remain optimal?
The rate would decrease.
The rate would remain the same.
The rate would increase.
The enzyme would denature.

Explanation

Increasing the substrate concentration generally increases the reaction rate until the enzyme becomes saturated with substrate.
