where is pepsin secreted in the digestive system?
stomach
the second vital secretion of the gi tract is that of digestive enzymes that are secreted in the mouth, stomach and intestines. some of these enzymes are secreted by accessory digestive organs, while others are secreted by the epithelial cells of the stomach and intestine. while some of these enzymes remain embedded in the wall of the gi tract, others are secreted in an inactive proenzyme form. when these proenzymes reach the lumen of the tract, a factor specific to a particular proenzyme will activate it. a prime example of this is pepsin, which is secreted in the stomach by chief cells. pepsin in its secreted form is inactive (pepsinogen). however, once it reaches the gastric lumen it becomes activated into pepsin by the high h+ concentration, becoming an enzyme vital to digestion. the release of the enzymes is regulated by neural, hormonal, or paracrine signals. however, in general, parasympathetic stimulation increases secretion of all digestive enzymes.
