As a result, the stomach is the main site of synthesis and function (pH 1.5 to 2). In humans, pepsin concentrations in the stomach range from 0.5 to 1 mg/mL.
WebPepsin had the highest rate of activity in a pH of 2.0. This correlates with pepsin's location in the stomach, which also has a low pH. What effect did boiling have on pepsin activity? Boiling pepsin denatured the enzyme causing it to have no effect on BAPNA. What is the substrate in this experiment?
WebThe optimum pH for pepsin activity of 1.0–2.0 is maintained in the stomach by HCl. When the pH of the medium increases to values greater than 3.0, pepsin is almost completely inactivated. In young children, gastric acidity is usually higher than in normal adults. In the first few months of life the gastric pH is approximately 5.0. impetigo school sores signs and symptomsWebNov 5, 2024 · Pepsin has maximal activity in acidic environments, ideally around a pH of about 1.5 to 2.
