Question

Which is correct about cell wall of bacteria and fungi ? Both have

• A. Glycopeptide
• B. N-acetylglucosamine
• C. N-acetylglucosamine and cellulose
• D. Chitin

Answer 1

Answer: (B)

N-acetylglucosamine

Bacterial cell wall is made up of N-acetylglucosamine and N-acetylmuramic acid, together called as mucopeptide. N-acetylglucosamine is found in the inner layer of both bacterial and fungal cell wall. It is commonly known as chitin. In plants, cell wall is made up of cellulose.

Thus, the correct answer is option C.
