Digestion and Absorption Out of Syllabus

Assertion is true and reason is false.

Cholecystokinin is a gastric hormone which is released in duodenum.

Cholecystokinin acts on pancreas and gall bladder and stimulates the secretion of pancreatic enzymes and bile juice.

The hormone gastrin is indeed released from the gastrointestinal tract and plays a significant role in digestion. Gastrin primarily stimulates the secretion of hydrochloric acid (HCl) by the parietal cells in the stomach, which lowers the pH and aids in digesting food. However, gastrin does not promote the secretion of trypsinogen.

Given this information, the appropriate option is :
