Answer:

The correct answer is - A bond forms between the carboxyl functional group of one amino acid and the amino functional group of the other amino acid.

Explanation:

A polypeptide is a polymer made up of amino acids linked together by peptide bonds. A peptide bond is formed between two amino acids in which the α-amino group of one amino acid is linked to the α-carboxyl group of another amino acid.  So peptide bonds are amide linkage.

This amide linkage is formed by the removal of one water molecule so it is a dehydration reaction. The linked amino acids are called amino acid residues. When many amino acids are joined together by the peptide linkage they are called polypeptides.

Therefore the correct answer is- A bond forms between the carboxyl functional group of one amino acid and the amino functional group of the other amino acid.
