Quizplus · Accepted Answer

Cholecystokinin (CCK) secretion is primarily stimulated by the presence of digestion products of proteins and fats in the duodenum. CCK plays a crucial role in digesting fats and proteins by stimulating the gallbladder to contract and release bile into the intestine and prompting the pancreas to secrete digestive enzymes.
