Question

Which one of the following is correct for structure of cell wall of fungi and bacteria?

• A. Both have glycopeptide.
• B. Both are made up of N-acetylglucosamine.
• C. Both are made up of N-acetylglucosamine and cellulose.
• D. Both are made up of chitin.

Answer 1

The correct option is B Both are made up of N-acetylglucosamine.

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.
