What is the optimum pH for catalase activity? A) 3.0 B) 7.0 C) 10.0 D) 13.0

Catalase is a common enzyme very important in reproductive reactions and is found in almost all living organisms exposed to oxygen. There are different catalase activities, pH optimum of which between 4 and 11 depending on the species. However, the optimum pH for human catalase is approximately 7.0 (letter C).
