• How Does Temperature Affect Catalase Enzyme Activity ...

    As the temperature increases toward the optimum point, hydrogen bonds loosen, making it easier for catalase to act on hydrogen peroxide molecules. If the temperature increases beyond the optimum point, the enzyme denatures, and its structure is disrupted. In humans, the optimum temperature for catalase is 37 degrees Celsius.
