Acinar cells do not produce
Answers
Answer:
Acinar cells are pyramidal, are oriented radially around a tiny, central lumen, and have intracytoplasmic, membrane-bound zymogen granules in the apical region. The more basophilic perinuclear region, containing the rough endoplasmic reticulum, gives the acinar cell a two-toned, apical–basal polarized appearance. Catalytically inactive precursor proteins (trypsinogen, chymotrypsin, procarboxypeptidase, proelastase, and kallikreinogen) are synthesized and stored in the zymogen granules, ready for release by granule fusion with the apical membrane when cells are stimulated by cholecystokinin and acetylcholine. Under normal physiological conditions, precursor enzymes are activated once they reach the lumen of the duodenum, through the sequential activation of trypsinogen to trypsin, followed by trypsin-mediated cleavage of other proenzymes
Acinar cells are the exocrine (exo=outward) cells of the pancreas that produce and transport enzymes that are passed into the duodenum where they assist in the digestion of food. Islets of Langerhans.
