Verified step by step guidance

Understand the role of enzymes in digestion: Enzymes are biological catalysts that speed up chemical reactions in the body, including the breakdown of food molecules during digestion.

Identify the function of each enzyme listed: Amylase breaks down carbohydrates, lactase breaks down lactose (a sugar found in milk), and lipase breaks down fats.

Recognize the specific enzyme responsible for protein digestion in the small intestine: Trypsin is an enzyme that specifically digests proteins by breaking down peptide bonds.

Learn where trypsin is active: Trypsin is secreted by the pancreas and becomes active in the small intestine, where it continues the digestion of proteins that began in the stomach.

Understand the importance of trypsin in the digestive process: Trypsin is crucial for the efficient breakdown of proteins into smaller peptides and amino acids, which can then be absorbed by the intestinal lining.
