Biology for IGCSE & O level - Enzymes (Section 1 - No. 47)
How does increasing the concentration of an enzyme affect the rate of a reaction, assuming the substrate concentration is not limiting?
The rate decreases.
The rate remains the same.
The rate increases proportionally.
The enzyme is denatured.
Explanation
Increasing enzyme concentration increases the reaction rate, as long as there is enough substrate.
