What type of prokaryotic cells contain lipopolysaccharides?
cells of bacteria are types of prokaryotic cells which contains lipopolysaccharides.
What is the function of Tris cl in extraction of DNA?
TRIS maintains the pH of the solution. Basically it interacts with the lipopolysaccharides present on the outer membrane which helps to permeabilize the membrane. This effect is enhanced with the addition of EDTA.
What chemical groups on gram negative might bacteriophage's attach?
A bacteriophage recognizes its host by its tail fibers binding to chemical groups associated with receptors on the surface of the host cell. Some of these receptors are transport proteins, pili, flagella and lipopolysaccharides. As you can see they have multiple jobs in the cell.
What is the arrangement of pseudomonas aeruginosa?
p.aureginosa do not have particular arrangement.Some said it has sarcina(package) arrangement but actually it can alter its package arrangement by binding of polycations to the lipopolysaccharides of p.aureginosa.
What are some examples of pyrogens?
Some examples of pyrogens are bacterial endotoxins, such as lipopolysaccharides (LPS) found in the outer membrane of gram-negative bacteria, and certain viral and fungal components. These substances can induce fever by activating immune cells to release cytokines such as interleukin-1 (IL-1) and tumor necrosis factor-alpha (TNF-α), which then act on the hypothalamus to raise body temperature.
What type of prokaryotic cells contain lipopolysaccharides?
cells of bacteria are types of prokaryotic cells which contains lipopolysaccharides.
Exotoxins are A proteins B only released after a cell is damaged or lysed C antiphagocytic factors D secretions that always target nervous tissue E lipopolysaccharides?
i am answering this question right now.they are not proteins, they are not lipopolysaccharides, they dont always target nervous tissue. so its either B or C
Why do bacterial cell walls carry a negative charge?
The Gram positive bacterial cell wall is made up of thick peptidoglycan layer which is rich in Teichoic acids. These teichoic acids are negatively charged because of presence of phosphate in their structure. The Gram negative bacteria have an outer membrane composed of phospholipids and Lipopolysaccharides. The lipopolysaccharides impart a strongly negative charge to surface of Gram negative bacterial cells.
What is endogenous endotoxin?
Endogenous endotoxin refers to lipopolysaccharides (LPS) that are produced by the body's own cells, particularly gut bacteria. These endotoxins can trigger an immune response and contribute to inflammation and other health issues when released into the bloodstream.

What is the difference between g plus ve and g-ve bacteria?
Primarily, the difference lies in their cell walls. G+ve bacteria have a thick peptidoglycan layer whereas G-ve bacteria have an outer membrane of lipopolysaccharides and proteins, a periplasmic space, and only a thin layer peptidoglycan.

Morphology of the gram-positive organism?
The gram positive cell wall contains a thicker layer of peptydoglacans than that of gram negative. the gram negative bacteria doesn't have a LPS(Lipopolysaccharides) covering outside the cell wall like the gram negatives.their is a periplasmal space between peptidoglycan cell wall and the cell membrane. During Gram's staining the CVI complex doesnt leave the gram positive bacteria because of the thick layer of peptydoglycanes.
Why it is necessary to prepare a bacterial smear?
For classification and identification purposes. Gram+ stain a dark purple/blue color while Gram - stain a red/pink color. This is due to the fact that Gram-positive cells have more peptidoglycan in their cell wall. Gram-negative cells don't have a think layer of peptidoglycan. They do have an outer layer of lipopolysaccharides and proteins which the Gram + does not have.
What is required to clot blood?
A lot of substances are involved in blood clotting. It is a very large and complex picture. Without writing a whole essay, the best I can do for you is make a short list of critical components: 1. A healthy bone marrow (this is where the platelets are produced) 2. A healthy liver (this is where most of the proteins of the clotting cascade are produced) 3. Vitamin K In addition, these common substances enhance blood clotting: 1. COX-2 inhibitors (any drug that ends with "coxib") 2. nicotine 3. bacterial products such as lipopolysaccharides
