Digestion of Which Organic Molecule Takes a Somewhat More Complicated

Question

Digestion of which organic molecule takes a somewhat more complicated route than most nutrients?
A) carbohydrate
B) fat
C) protein
D) nucleic acid

Accepted Answer

Fats undergo a more complicated digestion process than carbohydrates, proteins, or nucleic acids. They are first emulsified by bile salts in the small intestine, which breaks them down into smaller droplets, allowing enzymes like lipases to more efficiently break them down into fatty acids and glycerol. This process is more complex due to the fat's hydrophobic nature, requiring an emulsification step that is not necessary for the digestion of the other mentioned nutrients.
