All of the following are conjugated molecules except:
Correct answer: D. All of these
- A. Glycolipids
- B. Nucleoproteins
- C. Glycoproteins
- D. All of these
Explanation
Option D is correct. Two different molecules belonging to different categories, usually combine together to form conjugated molecules. Glycolipids are conjugated molecules. Conjugated molecules are molecules that contain a non-protein prosthetic group, which is a group of atoms that is not part of the amino acid chain of the protein. In the case of glycolipids, the prosthetic group is a carbohydrate. Nucleoproteins are conjugated molecules. Conjugated molecules are molecules that contain a protein covalently linked to another molecule, such as a nucleic acid, a lipid, or a metal ion. The protein in a nucleoprotein is called a nucleoprotein. The nucleic acid in a nucleoprotein is either DNA or RNA. Glycoproteins are conjugated molecules. Conjugated proteins are proteins that contain a non-protein prosthetic group, such as a metal ion, a nucleic acid, or a lipid. The prosthetic group in a glycoprotein is a carbohydrate, which is why glycoproteins are also called glycoconjugates.

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.
