A __________ consists of many monomers bonded together.

• monomer

• hydrocarbon

• peptide

• polymer (macromolecule)

Answer explanation

A polymer is the correct choice because it is a large molecule composed of many smaller units called monomers bonded together. Monomers are the individual units, hydrocarbons are compounds made of hydrogen and carbon, and peptides are short chains of amino acids, which are a specific type of monomer.

Proteins are made of monomers called ___________

• Nucleotides

• Monosaccharides

• Amino Acids

• Glycerol and fatty acids

Answer explanation

Proteins are made of monomers called amino acids.

All polymers (macromolecules) are made up of...

• monosaccharides

• monomers

• proteins

• None of these

Answer explanation

Polymers are large molecules composed of smaller units called monomers. These monomers are chemically bonded together in a repeating pattern to form the polymer.
