Since catalase is usually sensitive to pH variations and can be denatured or inactivated at extreme pH values, the addition of acid (HCI) is likely to reduce catalase activity. b. Since enzymes can be sensitive to variations in pH in the basic range, the addition of base (NaOH) may also reduce the activity of catalase. 4.
