    example, the enzyme we used in lab, cathechol oxidase, works only on the substrate catechol. Beacuse the enzymes are so specific they will only affect one direction of the reaction. Each enzyme works within quite a small pH range. There is a pH at which its activity is greatest (the optimal pH). This...
