Question

Quizplus · Accepted Answer

Lipopolysaccharides are a major component of the outer membrane of gram-negative bacteria and are responsible for many of their unique properties, including antigenicity and resistance to antibiotics. Amylose and cellulose are types of polysaccharides found in plant cell walls, while glycoproteins and lipoproteins are common components of all cell membranes, but not specific to the outer membrane of gram-negative bacteria.
