Catalysis is the process through which the rate of a reaction is altered while the quantity and chemical properties of the catalyst remain the same. Enzymes are a type of catalyst used to modify the rates of reactions in plants and animals. Enzymes can also be called biochemical catalysts. knaben bay unblocked
