Zymogenic cells of gastric gland secrete

  • pepsinogen

  • trypsin

  • pepsin

  • chymotrypsin


A.

pepsinogen

The peptic cells or chief cells or zymogenic cells of gastric gland secrete pepsinogen. The enzyme pepsinogen has no proteolytic activity. It is the inactive precursor of pepsin. The proenzyme pepsinogen on exposure to HCl gets converted into the active enzyme pepsin which is the proteolytic enzyme of the stomach.

Pancreatic acinar cells (exocrine part of pancreas) produce pancreatic juice that contains protein-digesting enzymes, namely trypsin, chymotrypsin and carboxypeptidase and carbohydrases like pancreatic a-amylase and lipase.
