Question

question 3 0.5 pts proteins are polymers constructed from ______ monomers. options: amino acid, hydrocarbon, lipid, nucleotide

Explanation:

To solve this, we recall the structure of proteins. Proteins are biological macromolecules (polymers) made by linking amino acids (monomers) through peptide bonds. Hydrocarbons are components of lipids or fuels, lipids are a different class of biomolecules (not monomers of proteins), and nucleotides are monomers of nucleic acids (like DNA/RNA), not proteins. So the correct monomer for proteins is amino acid.

Answer:

A. amino acid
