Biology for IGCSE & O level - Enzymes (Section 3 - No. 28)
How does temperature affect the activity of an enzyme?
As the temperature increases, enzyme activity decreases.
Enzyme activity is independent of temperature.
As the temperature increases, enzyme activity increases up to a certain point, after which it decreases.
As the temperature decreases, enzyme activity increases.
Explanation
As temperature rises, enzyme activity increases up to the optimum temperature; beyond that, it decreases due to denaturation.
