The main difference between endotoxins and exotoxins is their chemical composition and how they are produced. Endotoxins are lipopolysaccharides that are part of the outer membrane of Gram-negative bacteria and are only released when the bacteria are lysed. Exotoxins, on the other hand, are proteins that can be secreted by living bacteria and do not require bacterial death for release.
