(d) Secretin
Show Answer
Answer : b
Hints & Solution
(b) Cholecystokinin is a hormone which is secreted by the duodenal wall. It causes the release of bile by the contraction of the gall bladder & increases the enzyme release process of pancreatic cells. The pancreatic juice enterokinase is an ‘activator enzyme’ which is present in the intestinal juice (success entericus) and converts the inactive proenzyme trypsinogen to active trypsin enzyme. Secretin is also a hormone and causes the release of sodium bicarbonate in the pancreatic juice.
