Which of the following is NOT one of the three enzymes released by the pancreas?

The pancreas is known for producing a variety of digestive enzymes that play crucial roles in breaking down macromolecules in the small intestine. Among these enzymes, proteases break down proteins into peptides and amino acids; amylase is responsible for digesting carbohydrates, specifically starches into sugars; and lipase aids in the digestion of fats into fatty acids and glycerol.

Glucagon, on the other hand, is not a digestive enzyme but a hormone produced by the alpha cells of the pancreas. Its primary role is to raise blood glucose levels by stimulating the liver to release glucose into the bloodstream, especially during fasting or low-blood-sugar conditions. Therefore, its function is more related to glucose metabolism rather than digestion, distinguishing it from the enzymes you would find in the pancreatic secretions specifically aimed at breaking down food substrates.
