Step 1: Understand what enzymes are. Enzymes are special molecules that help speed up chemical reactions in living things.
Step 2: Learn about biomolecules. Biomolecules are large molecules that are important for life, and they include proteins, carbohydrates, lipids, and nucleic acids.
Step 3: Identify the type of biomolecule that enzymes belong to. Enzymes are made up of smaller units called amino acids, which are the building blocks of proteins.
Step 4: Conclude that since enzymes are made of proteins, they are classified as proteins.
