Question

which of the following is a component of the outer membrane in gram - negative bacteria that, in large amounts, can induce a lethal immunological response? multiple choice peptidoglycan phospholipid teichoic acids lipopolysaccharide flagellin

Explanation:

Lipopolysaccharide (LPS) is a major component of the outer - membrane of Gram - negative bacteria. In large amounts, LPS can induce a strong and potentially lethal immunological response, known as endotoxic shock. Flagellin is a protein that makes up flagella, teichoic acids are in Gram - positive cell walls, phospholipid is a general membrane component not specific to Gram - negative outer membranes in this context, and peptidoglycan is in the cell walls of both Gram - positive and Gram - negative bacteria but not the outer - membrane component that causes the described response.

Answer:

Lipopolysaccharide
