Beyond the optimum temperature, the activity of enzyme decreases, as at extreme temperature, the enzymes are denatured and its activity 1. . Effect of Temperature on Enzyme Inactivation Parameters As said above, temperature exerts opposite effects on enzyme activity and enzyme stability (see Fig. ) so temperature-explicit functions for inactivation parameters are required to determine the best temperature for a given process. Enzyme thermal inactivation of enzymes is the consequence of the weakening of the . After the optimal temperature, the reactions of the enzyme fall dramatically (Smith). This is caused because of the increased kinetic energy that has been formed by all the heat. With all this kinetic energy it causes the enzyme’s shape to break becoming denatured. ib business and management coursework hl
