Question

where are the lipopolysaccharides found?
a) both gram - positive and gram - negative
b) the gram - positive cytoplasm
c) the outer membrane of gram - negative bacteria
d) the gram - positive peptidoglycan

Explanation:

Lipopolysaccharides (LPS) are a major component of the outer membrane of Gram - negative bacteria. Gram - positive bacteria do not have an outer membrane with LPS. Gram - positive bacteria have a thick peptidoglycan layer, and their cell wall components are different from those of Gram - negative bacteria. LPS is not found in the cytoplasm of any bacteria.

Answer:

C. The outer membrane of Gram - negative bacteria
