Importances of temperature constant

If the temperature was too low: Enzyme rate of reactions would decrease due to decreased kinetic energy. This causes less ES complexes to form.   Homeostasis ensures that the internal temperature is maintained. This allows optimal enzyme reactions to occur; processes such as respiration occur continuously.   If the temperature is too high: Hydrogen and ionic bonds in the enzyme break. This alters the specific tertiary structure and alters the active site shape. The substrate is no longer complementary so ES complexes do not form.
