Optimum Temperature is 35°C
Optimum PH is 7.0.
Explanation:
The optimum temp of enzymes is 20-35°c. They become inactivated at very low temperature and denatured (destroyed) at very high temp i.e. greater than 45°C. Low molecular weight enzymes are comparatively more heat stable.
The optimum pH of most enzymes is pH 7.0 (neutral pH).
