Question

Which of the following statements accurately describes specific bacterial cell walls? View Available Hint(s) Which of the following statements accurately describes specific bacterial cell walls? Gram-negative bacterial cell walls contain teichoic acids, whereas the cell walls of gram-positive bacteria do not. The cell walls of gram-negative bacteria contain many more layers of peptidoglycan than those of gram-positive bacteria. In gram-negative bacteria, the thin layer of peptidoglycan is surrounded by an outer membrane made of phospholipids, lipopolysaccharides, and proteins. In bacteria with acid-fast cell walls, the carboxylic acid in the walls forms a layer outside a thin layer of hydrophilic polypeptides.

Answer 1

Answer:

In gram-negative bacteria, the thin layer of peptidoglycan is surrounded by an outer membrane made of phospholipids, lipopolysaccharides, and proteins. This statement accurately describes specific bacterial cell walls.

Explanation:

The Gram- negative bacteria constitute of an outer membrane which is richly made up of lipopolysaccharides, phopholipids and proteins. The lipopolysaccharides function mainly as a virulence factor and are involved in causing variety of diseases in animals.

Gram- negative bacteria can be seperated from gram- positive bacteria mainly because of the thickness of peptidoglycan and by the presence of the outer membrane of Gram- negative bacteria. The outer membrane is absent in Gram- positive bacteria.
