Making the world better, one answer at a time. It depends on what type of Enzyme. Enzymes have different optimum pH depending on the environment they work in, for example and enzyme in the stomach of a human would have a pH of about 2 but an enzyme in human saliva has an optimum pH of 5.6.
Different enzymes have different Optimum pH values. This is the pH value at which the bonds within them are influenced by H+ and OH- Ions in such a way that the shape of their Active Site is the most Complementary to the shape of their Substrate. At the Optimum pH, the rate of reaction is at an optimum.
