One of the constituents of the pancreatic juice while poured into the duodenum in humans, is:
trypsinogen
chymotrypsin
trypsin
enterokinase
As we learned in
Enzymes in the Pancreatic Juice -
The pancreatic juice contains inactive enzymes – trypsinogen, chymotrypsinogen, procarboxypeptidases, amylases, lipases and nucleases.
-
Trypsinogen -
Trypsinogen is activated by an enzyme, enterokinase
- wherein
Secreted by the intestinal mucosa into active trypsin, which in turn activates the other enzymes in the pancreatic juice.
Regions in Small Intestine -
Duodenum
- wherein
The duodenum is a short structure ranging from 20 cm (7.9 inches) to 25 cm (9.8 inches) in length, and shaped like a "C". It surrounds the head of the pancreas. It receives gastric chyme from the stomach, together with digestive juices from the pancreas (digestive enzymes) and the liver (bile). The digestive enzymes break down proteins and bile emulsifies fats into micelles. The duodenum contains Brunner's glands, which produce a mucus-rich alkaline secretion containing bicarbonate. These secretions, in combination with bicarbonate from the pancreas, neutralize the stomach acids contained in gastric chyme
