To address the question regarding the hormones secretin and CCK (cholecystokinin) and their action on the pancreas, let's explore the roles of these hormones and the enzymes mentioned.

1. Secretin Function: Secretin primarily stimulates the pancreas to release bicarbonate-rich fluid that neutralizes stomach acid in the small intestine. It indirectly supports the release of digestive enzymes.

2. CCK Function: CCK plays a role in stimulating the pancreas to secrete digestive enzymes, particularly those involved in the digestion of fats and proteins.

3. Enzymes Overview:

   • Gastrin: This hormone is produced in the stomach and stimulates gastric acid production, not released by the pancreas.
   • Pepsin: This is a stomach enzyme active in the acidic environment of the stomach; it is not secreted by the pancreas.
   • Trypsin: Released by the pancreas, trypsin is an enzyme that digests proteins in the small intestine.
   • Chymotrypsin: Also produced by the pancreas, it functions similarly to trypsin in protein digestion.

Analysis

• From the above functions, it's clear that the hormones secretin and CCK directly stimulate the release of digestive enzymes from the pancreas, specifically trypsin and chymotrypsin.

Final Answer

The correct selections are:

• Trypsin
• Chymotrypsin
