an enzyme does not get used up in a reaction. it is essentially a catalyst. although an enzyme speeds up the rate of chemical reactions by decreasing the amount of activation â¦ energy required, it does not in itself change during the reaction.***Note:: Enzymes cease to function when they denature.This usually occurs by pH level changes, or increased temperatures.nzymes speed up the rate of chemical reactions by lowering the energy of activation (the amount of energy needed to begin a reaction). 18 people found this useful.
