Chief Cells secrete pepsinogen, which turns into pepsin when it is exposed to HCl. Intrinsic Factor and Pepsinogen are also secreted by Chief Cells. Pepsin is activated by HCl.
Sri K.
Chief cells within the stomach lining are responsible for production and secretion of pepsinogen; the precursor of the enzyme pepsin. Pepsin is responsible for the digestion of proteins. Predict the most likely pathway of the secretion of pepsinogen by chief cells: ER → lysosomes → vesicles that fuse with plasma membrane Golgi apparatus → ER → lysosomes nucleus → ER → Golgi apparatus ER → Golgi apparatus → vesicles that fuse with the plasma membrane
