- The stomach has two types of exocrine cells: the chief cells, which secrete an inactive form of the protein-digesting enzyme pepsinogen, and the parietal cells, which secrete hydrochloric acid (HCl) that activates pepsinogen. Both cell types have an abundance of mitochondria for ATP production- the chief cells need energy to synthesize pepsinogen, and the parietal cells need energy to transport hydrogen ions. (H+) and chloride ions (Cl-) from the blood into the stomach lumen. Only one of these cell types has an extensive rough endoplasmic reticulum and abundant Golgi stacks. Would this be the chief cells or the parietal cell? parietal cells.Although rabbits cannot digest the cellulose in their all-plant diet, bacteria that live in their cecum can.
