Exotoxins are protein toxins secreted by (+ or -) bacteria into the environment. Endotoxin is usually LPS (lipopolysaccharide), or another component of the cell membrane of Gram-negative bacteria. LPS creates a toxic immune response when released (by cell lysis) into an animal's body.n endotoxin is part of the outer portion of the cell wall of gram-negative bacteria. They are released when the bacteria die and the cell wall breaks apart. They differ from exotoxins in that they are lipopolysaccharides not proteins.
