What happens to nutrient macromolecules in an animal's digestive tract?
A) They are absorbed whole and are then broken down into monomers within cells that ultimately use them. B) Proteins and nucleic acids are digested into monomers before absorption; energy-storage macromolecules (starch and fat) are absorbed whole. C) The digestive breakdown of macromolecules determines the monomers that are immediately needed and therefore produced. D) Nutrient macromolecules are digested into monomers before absorption.
