Unit 1 Biochemistry Concept Review

How are monomers and polymers different? Provide an example of each.

• Monomers are made up of multiple units, while polymers are single units. For example, water is a monomer, and cellulose is a polymer made up of many water molecules.
• Monomers and polymers are the same thing. For example, glucose is both a monomer and a polymer.
• Monomers are single units, while polymers are made up of multiple monomers bonded together. For example, glucose is a monomer, and starch is a polymer made up of many glucose molecules.
• Monomers and polymers are both made up of multiple units. For example, amino acids are monomers, and proteins are polymers made up of many amino acid molecules.
