Optimal temperature for catalase activity
WebThe optimum PH of human catalase is approximately 7 and the optimum temperature is at 37 degree. Both the PH optimum and temperature for other catalases varies depending on the species. Catalase can be inhibited by a flux of O 2- generated in situ by the aerobic xanthine oxidase reaction. WebExposure of catalase to temperatures up to 40°C. for 1 hour causes practically no inactivation. Inactivation begins at about that temperature reaching a maximum at about …
