GIT GI hormone with glucose, amino acids, and fatty acids!

A. CCK (Cholecystikin)
B. Motilin
C. Gastrin

I'll go with GIP (which is Glucose Insulinotropic Peptide btw)

Its released by Glucose/AA/Fatty Acids

Qurat21: Motilin as you mentioned forms MMCs, which occur when you're starving! (Stomach rumbling lol)

Correct Answer

The correct answer is D.
GIP is the only gastrointestinal hormone that is secreted in response to all three types of nutrients. Secretin is secreted in response to fatty acids (and H+) in the duodenal lumen, and CCK in response to small peptides, amino acids and fatty acids. Gastrin is secreted by G cells of the stomach (not the duodenum). Motilin is secreted by cells of the duodenum but in the fasting state.
