Parietal cells pepsinogen
WebThe correct answer is parietal cells. Parietal cells are responsible for HCl secretion in the stomach, which lowers the overall pH of the stomach. Chief cells secrete pepsinogen, which is converted to pepsin and is responsible for digesting proteins. G cells secrete gastrin, which stimulates parietal cells. Report an Error WebDec 27, 2024 · The first cell lineages to expand in number and activity are surface mucous and parietal cells (PC), which are followed by mucous neck (MNC), zymogenic (ZC) and endocrine cells [1,2,25,26,27]. PC are identified as round eosinophilic cells that use a membrane canaliculi system to pump H + and transport Cl - , but they also synthesize the ...
