Absorption of all the major nutrients (fat, protein, polysaccharide) from the gut has which of the following characteristics?

Question

Quizplus · Accepted Answer

Absorption of all major nutrients requires hydrolysis of larger molecules (such as fats, proteins, and polysaccharides) into smaller subunits. The smaller subunits can then be absorbed across the intestinal epithelium and into the bloodstream. Active transport is required for some nutrients, but not all. ATP hydrolysis may be involved in some active transport processes, but it does not always result in useful work and may instead be dissipated as heat. Absorption can result in entry into the portal circulation or lymphatic system, depending on the nutrient and the transport mechanism involved. Phosphorylation is not always required for absorption.
