Which statement describes how polymerization relates to proteins and amino acids?
many different proteins join together to form an amino acid.
many different amino acids join together to form a protein.
a single large protein breaks down to form many amino acids.
a single large amino acid breaks down to form many proteins.

The statement “Many different amino acids join together to form a protein” best describes polymerization. Amino acids are the basic molecules in proteins. Polymerization is the bonding of two or more molecules in order to create a larger molecule, which in this case is protein. The bonding agent between the amino acids is called the peptide bond.
