Which one of the following reactions results in the conversion of amino acids to proteins?
Correct answer: A. Condensation
- A. Condensation
- B. Deamination
- C. Hydrolysis
- D. Phosphorylation
Explanation
The correct answer is condensation. This reaction involves the joining of amino acids through the formation of peptide bonds, releasing a molecule of water in the process. This is how proteins are synthesized. The other options are incorrect because they describe different biochemical processes: deamination involves removing an amino group from an amino acid, hydrolysis involves breaking molecules down by adding water (contrary to building up proteins), and phosphorylation involves adding a phosphate group, which does not pertain to protein synthesis from amino acids.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
