Which component is a characteristic feature of the outer membrane of Gram-negative bacteria?
Correct answer: C. Lipopolysaccharide layer
- A. Teichoic acid layer
- B. Thick peptidoglycan layer
- C. Lipopolysaccharide layer
- D. Chitinous cell wall
Explanation
Lipopolysaccharide is a major component of the outer membrane of Gram-negative bacteria and includes lipid A, core polysaccharide, and O antigen. Teichoic acids and a thick peptidoglycan layer are associated mainly with Gram-positive bacteria, while chitin is not a bacterial wall component.
