What are the components of gram negative and gram positive cell walls?
Components of Gram positive Cell Wall | Components of Gram Negative Cell Wall |
Consists of many layers of peptidoglycan(60-90%). | Contains only one layer of peptidoglycan layers(10-20%). |
Consists of Techoic acids and Lipotechoic Acids. | Outer membrane is composed of phospholipids, lipopolysaccharides and proteins. Pore forming proteins called porins span the outer membrane. |

Gram-positive and gram-negative bacteria differ in that A. Gram-positive bacteria have more peptidoglycan in their cell walls. B. Gram-positive bacteria have fimbriae but gram-negative bacteria do not. C. Gram-positive bacteria are spiral-shaped, and gram-negative bacteria are either rod-shaped or spherical. D. Only gram-negative bacteria can form endospores. E. There is no difference between gram negative and gram positive bacteria F. Gram positive are positively charged and gram negative are negatively charges An unknown bacterial species was found in the blood...
xompare and contrast the cell walls of fram postuve and gram negative bacteria. why are the drugs that target cell wall synthesus useful? are drugs that target cell wall synthesus effective for all bacteria
43.Lipopolysaccharides (LPS) are found in: a. Gram-positive bacteria b. Gram-negative bacteria c. all Bacteria d. Archaea e. Eukaryotes ------------------------- 44. There are similarities and differences between Gram-negative and Gram-positive bacteria. Which of the following is not true? a. The cell wall of Gram-negative cells is composed of only one or two layers of peptidoglycan whereas the cell walls of Grampositive bacteria have many peptidoglycan layers b. Only Gram-positive bacterial cells have a periplasm 2/6/18 8 c. The cell membranes of...
List three technical reasons that a normal gram-negative cell might stain as if it were gram-positive. For each, explain the reason that this result would be observed.
20.) The term spheroplast applies to a gram-negative bacterial cell which .......? A.) is likely to lyse due to the osmosis shock b.) is just about to ready to produce a spore c.) is fighting off an infection by becteriophages d.) has lost its peptidoglycan layer of the cell wall e.) is lacking a cell wall 17) Peptidoglycan is a polymer consisting of the following chemical constituents (1 pts) ON-acetyglucosamine (AGA), N-acetylmuramic acid, and a peptide chain ON-AGA, N-AMA, teichoic...
Part A Which of the following statements accurately describes bacterial cell walls? In bacteria with acid-tast cell walls, the carboxylic acid in the walls forms a layer outside a thin layer of hydrophilic polypeptides. The cell walls of gram-negative bacteria contain many more layers of peptidoglycan than those of gram-positive bacteria. In gram-negative bacteria, the thin layer of peptidoglycan is surrounded by an outer membrane made of phospholipids, lipopolysaccharides, and proteins Gram-negative bacterial cell walls contain teichoic acids, whereas the...
Answer all Identify whether the following are true of Gram-positive or Gram-negative bacteria. Has a cell wall Has a second outer membrane Contains the molecule LPS, which triggers an immune response through TLR proteins Contains the bacteria that cause cholera Ampicillin and amoxicillin are specific to this type as they block peptidoglycan production
