Question

14. What in pepsinogen and write in active form​

Answer 1

pepsinogen or pepsin is secreted in stomach. it digests proteins. pepsin is active form

Answer 2

Pepsinogen, inactive precursor form of pepsin, is secreted by Chief cells in the stomach. Pepsinogen is activated by Hydrochloric acid (secretion from Parietal cells) because Hydrochloric acid provides the necessary acidic environment for which pepsin works best. Once pepsinogen becomes pepsin, it is responsible for the breakdown of food. The difference between pepsinogen and pepsin is that its primary structure has an additional 44 amino acids. The activation of pepsinogen to pepsin makes pepsin available to catalyze pepsinogen further to cleave it into more pepsin.
