Question

Gram-negative cell wall contains an outer membrane called the lipopolysaccharide (LPS). This LPS is found in the outer leaflet of the outer membrane. The innermost portion of the LPS is called Lipid A, which is an endotoxin. When are endotoxins released from a bacterial cell?

Answer 1

Answer:

The correct answer is - during active cellular growth and after cell lysis

Explanation:

Endotoxins, also known as LPS, are part of the outer leaflet of the outer membrane of the cell wall of gram-negative bacteria. These LPS especially Lipid A LPA released into the circulation when there is a disruption of the intact bacteria or after cell lysis. These are present in cell-associated bacteria such as Gram-negative pathogens such as Escherichia coli, Salmonella, Shigella, Pseudomonas, and others.
