What is the difference between cell wall of gram positive and gram negative bacteria.?
Gram positive bacteria cell walls have a thick layer of Peptidoglycan and no periplasmic space. Gram negative bacteria cell walls have inner and outter cytoplasmic membranes with a periplasmic space in between. these also have a thin layer of Peptidoglycan. The outter cytoplasmic membrane of gram negative bacteria contains lipopolysaccharides.
Do bacteria have a cell wall?
Yes, bacteria have a cell wall. It helps to maintain their shape and provides protection from the external environment. The cell wall of bacteria is made of peptidoglycan.
What is myoplasma?
Mycoplasma is a type of bacteria that lack a cell wall and are known to cause respiratory infections in humans, such as walking pneumonia. They are often treated with antibiotics that are effective against this type of bacteria.
Does a bacteria cell have a cell wall and a cell membrane?
Yes, bacteria have both a cell wall and a cell membrane. The cell wall provides structural support and protection to the cell, while the cell membrane controls the movement of substances in and out of the cell.
What is the function of the cell wall in the cell wall?
it protects the cell wall from any bacteria virus, and other enffections
What cell wall is toxic to humans?
The cell wall of certain bacteria, such as gram-negative bacteria, contains lipopolysaccharides that can be toxic to humans when they are released into the body. This can trigger an immune response leading to inflammation and potentially serious health effects.
What is the least toxic type of antimicrobial drug on humans?
Inhibits the synthesis of the peptidoglycan (or cell wall).
What is the difference between cell wall of gram positive and gram negative bacteria.?
Gram positive bacteria cell walls have a thick layer of Peptidoglycan and no periplasmic space. Gram negative bacteria cell walls have inner and outter cytoplasmic membranes with a periplasmic space in between. these also have a thin layer of Peptidoglycan. The outter cytoplasmic membrane of gram negative bacteria contains lipopolysaccharides.
What do Mycoplasma bacteria lack?
Mycoplasma is a genus of bacteria that lack a cell wall. They can be parasitic or saprotrophic, with some considered to be pathogenic in humans.
Do bacteria have a cell wall?
Yes, bacteria have a cell wall. It helps to maintain their shape and provides protection from the external environment. The cell wall of bacteria is made of peptidoglycan.
Why doesn't penicillin kill humans?
The penicillin kills bacteria by interfering with repairs to the bacterial cell wall. Human cells don't have a cell wall, and don't use the same enzymes that make the bacteria vulnerable.
Do methanol kill bacteria?
Yes, methanol can kill bacteria due to its toxic and denaturing effects on their cellular proteins. However, it is not generally used as a disinfectant due to its high toxicity to humans.
What is myoplasma?
Mycoplasma is a type of bacteria that lack a cell wall and are known to cause respiratory infections in humans, such as walking pneumonia. They are often treated with antibiotics that are effective against this type of bacteria.
Does bacteria have a cell wall?
Yes, most bacteria have a cell wall. The cell wall helps provide structure and support to the bacterial cell, as well as protect it from external threats. The composition of the cell wall can vary among different types of bacteria.
Do all bacteria have a cell wall?
No, not all bacteria have a cell wall. Bacteria can be classified into two main groups based on the presence or absence of a cell wall: Gram-positive bacteria have a thick cell wall, while Gram-negative bacteria have a thin cell wall surrounded by an outer membrane. Some bacteria, like Mycoplasma species, lack a cell wall altogether.
What is the type of coating on a bacteria cell?
In bacteria, the cell wall is composed of peptidoglycan, and is essential to the survival of many bacteria. Bacteria have been classified into Gram-positive and Gram-negative based on the structure of the cell wall. Gram-positive bacteria possess thick cell wall consisting of many layers of peptidoglycan and teichoic acids. Gram-negative bacteria have relatively thin cell wall consisting of few layers of peptidoglycan.
What is the outer cell wall of a bacterial cell made of?
The outer cell wall of a bacterial cell is typically made of peptidoglycan, a complex molecule composed of sugars and amino acids. This structure provides rigidity and protection to the cell, helping to maintain its shape and resist changes in osmotic pressure.
