The optimal temperature for catalase to the physiological conditions of a cell is 37 degree Celsius. The optimal pH for the enzyme is neutral, that is, 7.0. Catalase is generally used by the majority of animals to catalyze hydrogen peroxide into water and oxygen.  

Hydrogen peroxide is one of the harmful byproducts of certain kind of metabolic procedures and must be transformed quickly post creation to inhibit damage.
