The molecular mechanisms by which environmental changes are able to produce changes in the enzymatic capacity of the cells have intrigued scientists for many years, and recently some of these mechanisms have been elucidated. Studies concerning the manner in which the environment affects enzymatic processes have centered on the effect on enzyme activity, and the effect on enzyme synthesis...
