he stomach has two types of exocrine cells, chief cell which secrete an inactive form of the protein degesting enzymes pepsinogen, and parietal cells , which secrete hydrochloric acid that activates pepsinogen.Both cell types have an abundance of mitochondria ATP production.The chief cells need energy to synthesise pepsinogen and parietal cells need energy to transport hydrogen ions and chloride ions from the blood into the stomach lumen.Only one of this cell types has an extensive roung endoplasmic and abandant Golgi stacks. Would this be the chief cells or parietal cells?why?
