Question

in the adult digestive tract, where do lipases break fat into fragments so that it can be absorbed into the lymph?
o a. mouth
o b. stomach
o c. small intestine
o d. large intestine

Explanation:

Lipases are enzymes that break down fats. In the adult digestive tract, lipase - mediated fat digestion mainly occurs in the small intestine. The small intestine has the appropriate environment (including bile from the liver and pancreatic lipase) for the efficient breakdown of fats into fragments that can be absorbed into the lymph (in the form of chylomicrons). The mouth has salivary amylase (for carbohydrate digestion), the stomach has pepsin (for protein digestion in an acidic environment), and the large intestine is mainly involved in water absorption and feces formation.

Answer:

c. Small intestine
