Effect of Varying Temperatures: The enzyme catalyzed reaction rate during varying incubation temperatures are plotted on Figure. 6. As the temperature increases the rate increases‚ but as the temperature reaches 49oC it begins to drop. When the plot of the logarithm of the rate is used against the inverse of the temperature kelvin’s the Arrhenius equation is used to calculate the activation energy. The range in orange is between 16.5 - 37oC and the activation energy is calculated to be 9332kcal/mol
