Verified step by step guidance1
Understand the role of the pancreas in digestion: The pancreas is a vital organ that secretes digestive enzymes into the small intestine to aid in the breakdown of carbohydrates, proteins, and fats.
Identify the enzymes secreted by the pancreas: The pancreas secretes several key enzymes, including amylase, lipase, and trypsin.
Explain the function of each enzyme: Amylase helps in the digestion of carbohydrates by breaking down starches into sugars. Lipase is responsible for breaking down fats into fatty acids and glycerol. Trypsin aids in protein digestion by breaking down proteins into smaller peptides.
Differentiate pancreatic enzymes from other digestive enzymes: Note that enzymes like sucrase, isomaltase, and enterokinase are not secreted by the pancreas but are instead produced by the cells lining the small intestine.
Conclude with the correct answer: Based on the functions and origins of these enzymes, the correct answer to the problem is that the pancreas secretes amylase, lipase, and trypsin into the small intestine.
