The chitinous exoskeleton of arthropods is formed by the polymerization of:
Correct answer: C. N - acetyl glucosamine
- A. D-glucosamine
- B. lipo glycans
- C. N - acetyl glucosamine
- D. Keratin sulphate and chondroitin sulphate
Explanation
This is the correct answer. The chitinous exoskeleton of arthropods is formed by the polymerization of N-acetylglucosamine, a derivative of glucose. Chitin is a long-chain polymer of N-acetylglucosamine. Therefore, the correct answer is option C: "N-acetylglucosamine."

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.
