8.2.3.1 Effect of pH

Enzymes have a characteristic optimum pH at which their activity is generally between 5 and 9. The optimum pH of pepsin:1.5, salivary amylase: 6.8., trypsin: 8.0,and intestinal :7.8. A small change in pH may inhibit enzyme activity. Pepsin work in acid medium and it is in activated by making the medium alkaline. Diagram explains the effect of pH on enzyme activity.
