The Wonderful World of Prokaryotes

Lipid A = Toxic portion of LPS that can cause septic shock LPS = Structural feature of the outer membrane of Gram-negative cell, comprised of lipopolysaccharides Cocci = Roughly spherical cells that can form long chains in certain genera Prokaryotes = Organisms that lack a membrane-bound nucleus and other internal structures

Lipid A = Part of LPS that can act as a toxin Core polysaccharide = Part of LPS that is located between lipid A and the O side chain O side chain = Part of LPS that is located on the outermost end of the molecule LPS = Large, complex molecule that contains both lipid and carbohydrate

Gram-negative cell = Cell type with a distinctive outer membrane structure, composed of lipopolysaccharides Septic shock = Condition that can develop if LPS or lipid A enters the bloodstream Streptococcus, Enterococcus, and Lactococcus = Genera that exhibit long chains of cocci Toxin = Lipid A can act as this if it enters the bloodstream

<p>Periplasm = Region between the inner and outer leaflets of the Gram-negative cell's outer membrane Outer leaflet = Part of the Gram-negative cell's outer membrane that faces the environment Inner leaflet = Part of the Gram-negative cell's outer membrane that faces the periplasm Endotoxin = Term used to describe the toxic effects of lipid A if it enters the bloodstream</p> Signup and view all the answers
