Explanation: 

Detailed explanation-1: -The two major pancreatic enzymes that digest proteins in the small intestine are chymotrypsin and trypsin . Trypsin activates other protein-digesting enzymes called proteases, and together, these enzymes break proteins down to tripeptides, dipeptides, and individual amino acids.

Detailed explanation-2: -Amylase is responsible for the breaking of the bonds in starches, polysaccharides, and complex carbohydrates into easier to absorb simple sugars. Salivary amylase is the first step in the chemical digestion of food.

Detailed explanation-3: -Exocrine Function: The pancreas contains exocrine glands that produce enzymes important to digestion. These enzymes include trypsin and chymotrypsin to digest proteins; amylase for the digestion of carbohydrates; and lipase to break down fats.
