Question

Which one of the following is correct for structure of cell wall of fungi and bacteria?
  1. Both have glycopeptide.
  2. Both are made up of N-acetylglucosamine.
  3. Both are made up of chitin.
  4. Both are made up of N-acetylglucosamine and cellulose.

A
Both are made up of chitin.
B
Both have glycopeptide.
C
Both are made up of N-acetylglucosamine.
D
Both are made up of N-acetylglucosamine and cellulose.
Solution
Verified by Toppr

Fungi have a cell wall consisting largely of chitin and other polysaccharides. True fungi do not have cellulose in their cell walls.
Chitin is a polymer consisting mainly of unbranched chains of (1, 4)-linked-N-acetylglucosamine, or poly-(1, 4)-linked-N-acetylglucosamine (chitosan).
Bacterial cell wall is composed of peptidoglycan, which is composed of N-acetylmuramic acid and N-acetylglucosamine.
Thus, the correct answer is option B.
