Final answer:

When the outer membrane of dead Gram-negative cells disintegrates, it releases Lipid A, which is part of the toxin called lipopolysaccharide (LPS).

Step-by-step explanation:

When the outer membrane of dead Gram-negative cells disintegrates, it releases Lipid A, which is part of the toxin called lipopolysaccharide (LPS). LPS is composed of Lipid A embedded in the outer membrane, a core polysaccharide, and an O side chain. Lipid A is responsible for the toxic properties of LPS and triggers the immune system's inflammatory response.
