Verified step by step guidance

Begin by identifying the function of each enzyme listed in the options. Understand that enzymes are biological catalysts that speed up chemical reactions in the body.

Recognize that the pancreas produces several enzymes that aid in digestion, each targeting specific types of nutrients: proteins, carbohydrates, and fats.

Understand that trypsin is a pancreatic enzyme specifically responsible for breaking down proteins into smaller peptides in the small intestine. It is activated from its precursor, trypsinogen, by the enzyme enterokinase.

Lactase is an enzyme that breaks down lactose, a sugar found in milk, into glucose and galactose. It is not involved in protein digestion.

Amylase is an enzyme that catalyzes the hydrolysis of starch into sugars, and lipase is responsible for breaking down fats into fatty acids and glycerol. Neither amylase nor lipase is involved in protein digestion.
