Enzymes have a globular structure.Heat provides energy to the molecules and they start vibrating above a certain critical temperature and thus destroy the protein structure necessary for activity. It is the chemistry of every molecule that on providing energy like in form of heat its motion always increase,may upto a vigorous level. On the other hand low temperature is meant for slowing down their motions thus making it inactive.When the enzyme reaches  suitable temperature its activity is restored. enzymes
