A) eubacteria Gram positive
B) eubacteria Gram negative
C) all eukaryotes
D) Both (a) and (b)
Correct Answer: B
Solution :
In Gram negative bacteria, the outer membrane is covered by lipopolysaccharides. The lipopolysaccharides consist of complex polysaccharides covalently linked to lipid A. Lipid A has endotoxin properties, while the polysaccharides have antigenic properties. The envelope of Gram-positive bacteria consists of a peptidoglycan wall, underlying, which is the cytoplasmic membrane. Associated with the peptidoglycan are phosphorus containing acidic polymer called teichoic acids, acidic polysaccharides such as teichuronic acids.You need to login to perform this action.
