The Absorption of Fats Differs from That of Carbohydrates in That

Question

The absorption of fats differs from that of carbohydrates in that the
A) processing of fats does not require any digestive enzymes, whereas the processing of carbohydrates does.
B) fat absorption occurs in the stomach, whereas carbohydrates are absorbed from the small intestine.
C) carbohydrates need to be emulsified before they can be digested, whereas fats do not.
D) most absorbed fat first enters the lymphatic system, whereas carbohydrates directly enter the blood.
E) fats, but not carbohydrates, are digested by bacteria before absorption.

Accepted Answer

Most absorbed fat first enters the lymphatic system, whereas carbohydrates directly enter the blood. This is due to the fact that fats are too large to be transported directly into the bloodstream, and must first be packaged into lipoproteins and transported through the lymphatic system before entering the bloodstream. Carbohydrates, on the other hand, can be directly absorbed into the bloodstream from the small intestine.
