Enzymes: Classification, Kinetics and Inhibition · Zoology

Which factor does NOT affect enzyme activity?

  1. Temperature
  2. pH of solution
  3. Substrate concentration
  4. Light intensity
Show answer and explanation

Correct answer: Light intensity

Enzyme activity is governed by temperature, pH, and substrate concentration, which affect enzyme structure and substrate availability. Light intensity does not directly influence enzymatic reactions under standard physiological conditions.
