Bacterial cell wall made up of:
Correct answer: D. Amino acid & sugar
- A. Cellulose & pectin
- B. Cellulose & cutin
- C. Hemicellulose & chitin
- D. Amino acid & sugar
Explanation
Amino acids and sugar is correct.Cell-wall of bacteria is totally different from ordinary plant cell-wall. It is chemically complex and made up of amino acids, sugar and chitin but cellulose is totally missing. The cell-wall of most bacteria have unique macromolecule called peptidoglycan. It is composed of long glycan chains cross-linked with peptide fragments. In addition sugar molecules, teichoic acid, lipoprotein and lipopolysaccharides are also present.STB- Pg 102.
