The optimum pH of catalase is:
Correct answer: A. Slightly alkaline
- A. Slightly alkaline
- B. Highly acidic
- C. Highly alkaline
- D. Slightly acidic
Explanation
The optimum pH of catalase is slightly alkaline, with a range of 6.8 to 7.2. This means that catalase works best at a pH that is slightly higher than neutral. Catalase is an enzyme that is found in most cells, and it is responsible for breaking down hydrogen peroxide. Hydrogen peroxide is a toxic substance, so catalase is important for preventing cell damage.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
