Amylase is an enzyme that digests which type of macromolecule?

Explanation:
Amylase is about enzyme specificity for substrates, focusing on carbohydrates. It acts on starch, a carbohydrate, by breaking the glycosidic bonds in polysaccharides to produce smaller sugars such as maltose and dextrins (which are then further digested to glucose). This digestion begins in saliva and continues in the small intestine, reflecting its role in carbohydrate breakdown. The other options involve different macromolecules: lipids are digested by lipases, nucleic acids by nucleases, and proteins by proteases, so amylase does not target those.
