part 1: vocabulary matching: write the correct word on the line.
word bank: some words may be used more than once.
biomolecule, carbohydrate, lipid, protein, nucleic acid, polymer, monomer, enzyme, amino acid, nucleotide

1. molecule that provides the cell with immediate energy, often found as sugars or starches.
2. a large molecule made of repeating subunits.
3. biological catalyst that speeds up chemical reactions.
4. the basic building block of proteins.
