Protease is an enzyme that digests which type of macromolecule?

Explanation:
Proteases break down proteins by cleaving peptide bonds between amino acids. Proteins are long polymers built from amino acids, and proteases specifically hydrolyze the bonds linking those amino acids, producing smaller peptides or free amino acids that can be absorbed by the body. Enzymes are typically specialized for particular macromolecules, so other enzymes handle different targets: carbohydrases break down carbohydrates, lipases break down lipids, and nucleases break down nucleic acids. So, the enzyme described as protease is the one that digests proteins.
