Final answer:
Amino acids are the monomers that make up proteins. Each amino acid has a central carbon atom bonded to an amino group, a carboxyl group, and a hydrogen atom.
Step-by-step explanation:
The subject of this question is Amino acid. Amino acids are the monomers that make up proteins. Each amino acid has a central carbon atom bonded to an amino group (NH2), a carboxyl group (COOH), and a hydrogen atom.
