Leni [432]3 years ago
7 0

Answer:This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system. In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants.

If limulus ameboyte lysate turns into a gel when exposed to a sample, it means gramnegative bactera
saul85 [17]

Answer:

Gelation is the analytical signal used for the qualitative and quantitative detection of lipopolysaccharides. Bacterial endotoxins are lipopolysaccharides (LPS) located exclusively on the outer membrane of gram-negative bacteria; Their presence in injectable pharmaceutical products may be associated with problems during production, there are established endotoxin limits for this type of product. When the reagent is faced with solutions containing endotoxins, it produces gelling.

Explanation:

The LAL (Limulus Amebocyte Lysate) test is used to detect and quantify endotoxins associated with gram-negative bacteria. It is based on the amebocytes from the blood of the Limulus polifemus crab gel in the presence of minimal concentrations of endotoxin (ng / ml of blood ). It is positive in 60% of bacilli due to gram-negative enteric bacilli. The presence of endotoxins is determined by the formation of an insoluble gel or clot. The reaction requires the presence of divalent cations. The speed of the reaction depends on the endotoxin concentration, the pH and the temperature. The lysate contains a cascade enzyme system that is progressively activated in the presence of endotoxins. As a final result, the coagulable protein (coagulogen) is transformed into a gel (coagulin), which is the basis of the tube gel method.

zlopas [31]

Answer:

The correct answer is - surface, proteins, and sugars.

Explanation:

Adhesins are the appendages present on the surface of the pathogen that help these pathogens to attach to the host cell and surface of the host. Adhesins are the components that are virulence factor these are present in both viruses and bacteria.

The adhesin component is generally made up of mainly of the proteins and sugars which help them to adhere to the cell of the host.
