Question

Which of the following makeup proteins?


Amino acids


Citric acids


Hydrochloric acids


Nitric acids

Answer 1

Amino acids are the building blocks of proteins. Proteins are made up of long chains of amino acids that are linked together by peptide bonds. The other options (citric acids, hydrochloric acids, and nitric acids) are types of acids but do not play a role in the makeup of proteins.
