Stimulus for CCK hormone is___________?
Correct answer: A. Fat, Protein
- A. Fat, Protein
- B. Acid
- C. Base
- D. Both A & B
Explanation
Cholecystokinin, or CCK, is released mainly when fats and partially digested proteins enter the small intestine, and it stimulates pancreatic enzyme secretion and gallbladder contraction. Acid is the main stimulus for secretin, so students may select both A and B by confusing secretin's stimulus with CCK's.
