Q7 / 180 · NEET 2015 (Phase 2) · Botany

The chitinous exoskeleton of arthropods is formed by the polymerization of:

  • A
    D-glucosamine
  • Correct answer
    B
    N-acetylglucosamine
  • C
    Lipoglycans
  • D
    Keratin sulphate and chondroitin sulphate

Solution

The exoskeleton of Arthropods is made up of chitin. Chitin is a mucopolysaccharide made up of monomeric glucose derivative N-acetylglucosamine. It is found in the cell wall of fungi and also in the exoskeleton of crustaceans.
