An endotoxin is
A) the toxic portion of the LPS.
B) a toxin produced within archaeal cells.
C) a toxin known for its primary attack on the epidermis of mammals.
D) the toxin produced in the periplasm of most bacteria.

Endotoxin is produced by gram-negative bacteria. The outer layer of the gram-negative bacterial cell wall is made up of lipopolysaccharide. Lipopolysaccharide in gram-positive bacteria contains a lipid A portion that has O antigen and many polymers that act as endotoxin.

So endotoxin is the toxic portion of LPS. This toxin is released in the body when the immune cell attacks the bacteria which can cause fever, inflammation, anaphylactic shock in humans. So the right answer is A.

An endotoxin is A) the toxic portion of the LPS. B) a toxin produced within archaeal cells. C) a toxin known for its primary attack on the epidermis of mammals. D) the toxin produced in the periplasm of most bacteria.
