Question

Gram positive bacteria contain lipopolysaccharide (LPS) in their outer membrane outside the cell wall, whereas gram negative bacteria do not.

a. True
b. False

Answer 1

Gram-positive bacteria do not contain lipopolysaccharide (LPS) in their outer membrane outside the cell wall.

Step-by-step explanation:

Gram-negative bacteria have a thin cell wall composed of peptidoglycan, while Gram-positive bacteria have a thick cell wall made of peptidoglycan.

In addition, Gram-negative bacteria have an outer membrane that contains lipopolysaccharides and lipoproteins, while Gram-positive bacteria do not have an outer membrane.

Therefore, the statement that Gram-positive bacteria contain lipopolysaccharide (LPS) in their outer membrane outside the cell wall is false.
