Answer:
Correct Answer: D
Solution:
Chemically bacteria consists of N-acetylglucosamine, D-amino acids and a peptide cross-link of four or five amino acids.
All these chemicals together form a polymer called peptidoglycan (= murein or mucopeptide).
Some other chemical substances deposited on the cell wall are teichoic acid, protein polysaccharides, lipoproteins and lipopolysaccharides.
