What cells are responsible for producing stomach acid (HCI)? How are HCI produced? A.) parietal cells; hydrogen ions and chloride ions are combined in the cell's cytoplasm , and HCI is secreted out of the cell via exocytosis B.) parietal cells the hydrogen ions and the chloride ions must be produced separately in the cell and combined only when they move to lumen of the stomach C.)chief cells hydrogen ions and chloride ions are combined in the cell's cytopla and HCI is secreted out of the cell via exocytosis D.)Chief cells ; the hydrogen ions and the chloride ions must be produced separat in the cell and combined only when they move to lumen of the stomach

Hydrochloric acid (HCl) is a highly corrosive acid found in the stomach (T/F). HCl is, however, not actually made in the cytoplasm of the parietal cell; rather hydrogen and chlorine ions combine to form HCl in the lumen of the gastric glands (T/F). Select one: A. false; true B. true; true C. true; false D. false; false

The stomach has two types of exocrine cells: chief cells, which secrete an inactive form of the protein-digesting enzyme pepsinogen, and parietal cells, which secrete hydrochloric acid that activates pepsinogen. Both cell types have an abundance of mitochondria for ATP production. The chief cells need energy to synthesize pepsinogen, and parietal cells need energy to transport hydrogen ions and chloride ions 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 parietal cells? Why?

12. Chief cells produce and secrete the zymogen (inactive form) that must be activated. Parietal cells produce and secrete hydrochloric acid and intrinsic factor. If a patient does not have the second, they will develop pernicious anemia. The food bolus is called "chyme" once it reaches the stomach and then moves forward to the duodenum. Intrinsic factor is necessary for the absorption of vitamin B12 in the small intestine.
