Question

amylase is a biological catalyst that digests starch into simple sugar molecules in the pancreas. which best describes amylase?

fatty acid
lipid
protein
nucleic acid

Explanation:

Amylase is an enzyme, and enzymes are mostly proteins. Fatty acids are components of lipids, lipids are a different class of biomolecules (e.g., fats, oils), and nucleic acids (like DNA/RNA) have different functions (genetic information storage/transfer). So amylase, as a biological catalyst (enzyme), is a protein.
