Question

figure 1. formation of a peptide bond
which of the following best describes the formation of the bond shown in figure 1?
a an ionic bond is formed between a carbon atom of one amino acid and the nitrogen atom of the other amino acid.
b an ionic bond is formed when the negative charge of an oh group is balanced by the positive charge of a hydrogen ion.
c a covalent bond is formed between a carbon atom and a nitrogen atom along with the formation of h2o.
d a covalent bond is formed that replaces the hydrogen bond between the oh group and the h atom.

Explanation:

Peptide bonds are covalent bonds formed between the carboxyl - carbon of one amino acid and the amino - nitrogen of another amino acid through a dehydration synthesis reaction, releasing a water molecule ($H_2O$).

Answer:

C. A covalent bond is formed between a carbon atom and a nitrogen atom along with the formation of $H_2O$.
