Micelles are clusters of bile salts and lipids that escort lipids to enterocytes for absorption. Amylase is the enzyme that catalyzes the reaction that breaks down carbohydrates. Lipids are absorbed into lymphatic vessels called lacteals, while carbohydrates and proteins are absorbed into the bloodstream, due to lipids being nonpolar and requiring a different structure for absorption than polar carbohydrates and proteins.

1. 8 Clusters of bile salts, digested lipids, and other nonpolar substances that escort lipids to
enterocytes are called a. micelles, b. chylomicions. c. lacteals. d. pancreatic lipase. 9 The enzyme
that catalyzes the reaction that breaks down carbohydrates is a. pancreatic lipase. b. pepsin. c.
trypsin. d. amylase. 10 Explain why lipids are absorbed into a different structure than are
carbohydrates and proteins.
