Proteins are conducted in the body in the form of:
Correct answer: A. Amino acids
- A. Amino acids
- B. Polypeptides
- C. Enzymes
- D. Nucleic acids
Explanation
The correct answer is amino acids. Proteins are made up of amino acids, which are linked together in specific sequences to form polypeptide chains. These chains fold into specific shapes to become functional proteins. The other options are incorrect: "Natural proteins" is not a scientifically recognized term for the form in which proteins exist in the body; enzymes are proteins that act as catalysts in biochemical reactions, not the form they are conducted in; and nucleic acids are a different type of biological molecule entirely, involved in genetic information rather than protein formation.

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.
