It is secreted mainly into the gastric lumen and into circulation. D. So they act only in the stomach lumen and do not digest intracellular proteins E. They can start digesting dietary proteins more quickly 38. Furthermore, pepsin can activate additional pepsinogen autocatalytically. The main difference between pepsin and trypsin is that the pepsin is secreted by the gastric glands of the stomach whereas the trypsin is secreted by the exocrine glands of the pancreas.Furthermore, pepsin functions in an acidic medium while trypsin functions in an alkaline medium. Pepsin is the mature active form of the zymogen (inactive protein) pepsinogen. It is produced in the gastric chief cells of the . It is secreted mainly into the gastric lumen and into circulation. Pepsin's proenzyme, pepsinogen, is released by the chief cells in the stomach wall, and upon mixing with the hydrochloric acid of the gastric juice, pepsinogen activates to . 16 Votes) Pepsin. Pepsinogen is activated into the digestive enzyme pepsin when it comes in contact with acid produced by gastric parietal cells. pepsin, the powerful enzyme in gastric juice that digests proteins such as those in meat, eggs, seeds, or dairy products. Pepsin works its best in strong hydrochloric acid. In the gastric mucosa, pepsinogen II (PgII) is produced/secreted by glands in the mucus-secreting antral and cardia compartments, but also by the chief cells and the oxyntic glands.
