Select the correct statement about absorption.
A) Eighty percent of ingested materials have been absorbed by the end of the large intestine.
B) In the rare case that intact, whole proteins are transported across the mucosal endothelium, an immune response may be generated.
C) Carbohydrates diffuse across the mucosal endothelium and are then actively transported into blood capillaries.
D) Amino acid transport is linked to chloride transport.

Question

Quizplus · Accepted Answer

Intact, whole proteins should not be transported across the mucosal endothelium. If they are, they may be recognized as foreign and trigger an immune response, leading to allergic reactions or other adverse effects. Therefore, option B is the correct statement about absorption. Option A is false because the majority of absorption occurs in the small intestine, not the large intestine. Option C is also incorrect as carbohydrates are actively transported, not diffused, across the mucosal endothelium. Option D is partly correct, but amino acid transport is actually linked to sodium transport, not chloride transport.
