Answer:
The answer to your question is letter A.
Explanation:
a. A bond forms between the carboxyl functional group of one amino acid and the amino functional group of the other amino acid. This is the correct answer because peptide bonding is very specific, only happens between the amino group of one amino acid and the carboxyl group of another.
b. A bond can form between any carbon and nitrogen atom in the two amino acids being joined. The answer is incorrect because peptide bonding is very specific it can not happen between any carbon or any nitrogen.
c. Polypeptides form by condensation or hydrolysis reactions. This answer is wrong because hydrolysis does not occur instead of that water is form as a product of this reaction.
d. The reaction occurs through the addition of a water molecule to the am , this answer is wrong, water is formed in this reaction, water is a product of the reaction not a reactant.
The statement which is true about the formation of polypeptides from amino acids is;
Proteins are straight-chain polymers that form when the alpha carboxyl group and alpha-amino group link up through a peptide bond to form polypeptides.
Hydrolysis occurs after two peptides are formed because there is a loss of a water molecule. Polarity occurs since the two ends of the polypeptide chain are different, consisting of the alpha carboxyl group and alpha-amino groups.
