Question

most carbohydrate, lipid, and amino acid absorption takes place in the: a pancreas b stomach. c small intestine. d mouth.

Explanation:

The small intestine is the primary site for the absorption of carbohydrates, lipids, and amino acids. It has a large surface area due to the presence of villi and microvilli, which enhance absorption. The pancreas produces digestive enzymes but is not the site of absorption. The mouth is involved in digestion (e.g., starch digestion by amylase) but not major absorption. The stomach mainly digests proteins (e.g., via pepsin) and has limited absorption (e.g., of some water, alcohol).

Answer:

C. small intestine.
