Question
Fats and proteins in the chyme entering the small intestine trigger the release of:
Question 1Answer
a. Glucagon
b. CCK
c. HCl
d. Trypsin
e. Secretin
Solution
The correct answer is:
b. CCK (Cholecystokinin)
Here's why:
When fats and proteins enter the small intestine, they stimulate the cells in the intestinal wall to release a hormone called Cholecystokinin (CCK). CCK then signals the gallbladder to release bile (which helps in fat digestion) and the pancreas to release digestive enzymes (which help in protein digestion). Therefore, the presence of fats and proteins in the chyme entering the small intestine triggers the release of CCK.
