How is an enzyme affected by ph

Web7 apr. 2024 · So enzyme activity depends on pH interval. In the stomach, for example, the gastric juice has a very low pH, around 2, and there the enzyme pepsin acts to intensively digest proteins. In the duodenum, pancreatic secretions increase the pH of the enteric juice for the action of other digestive enzymes, for example, trypsin.

Web1 jul. 2014 · An example is the attraction between a -COO- ion of lysine and an -NH+ 3 ion of aspartic acid. Increasing the pH by adding a base converts the -NH+ 3 ion to a neutral -NH2 group. Decreasing the pH by adding an acid converts the –COO- ion to a neutral -COOH group. In each case the ionic attraction disappears, and the protein shape unfolds.
