Most enzymes perform in pH among 6 and 8, a range which corresponds to the general acidic level of blood and cells. There are enzymes though, which act only beneath very acid or very basic pH. Thus, enzyme activity based on a pH interval.

In the stomach, for illustration, the gastric juice has a much low pH, around 2, and there the enzyme pepsin performs intensively digesting proteins. In duodenum, pancreatic secretions raise the pH of the enteric juice for the act of other digestive enzymes, for illustration: trypsin.
