How pepsinogen is activated
Nettet29. mai 2024 · Pepsinogen is activated in the stomach lumen by hydrolysis, with the removal of a short peptide: H + ions are important for pepsin function because: … NettetPepsinogen is defined as the inactive enzyme that is secreted by the stomach wall and converted into the enzyme pepsin by gastric acid. The factors that convert Pepsinogen to Pepsin are: Pepsinogen is converted to pepsin which digests protein. Their production is stimulated by the presence of gastrin in the blood.
