Regulation of Pancreatic Secretion of Digestive Enzymes

The secretion of digestive enzymes from the pancreas is primarily regulated by the hormone cholecystokinin (CCK). When food, especially fats and proteins, enters the duodenum (the first part of the small intestine), CCK is released from the intestinal mucosa. This hormone then stimulates the pancreas to secrete digestive enzymes, including lipase, proteases, and amylase, which are crucial for breaking down fats, proteins, and carbohydrates, respectively.

Other factors like the presence of bile salts and dietary cholesterol may play roles in digestion but are not the main regulators of pancreatic enzyme secretion. The amount of food eaten can influence digestive processes, but again, it is CCK that directly regulates the release of the enzymes needed for digestion.

Final Answer

Correct answer: Cholecystokinin
