How does sodium hydroxide effectively kill bacteria?
Sodium hydroxide kills bacteria by disrupting their cell membranes and proteins, leading to cell death. This strong base can penetrate the bacterial cell wall, causing damage and ultimately destroying the bacteria.
What is a carbohydrate polymer composed of beta-glucose subunits?
A polymer composed of beta-glucose monomers is cellulose.
What will happen to the water inside bacteria when they are in an extremely salty environment?
In an extremely salty environment, water will move out of the bacteria through osmosis to try to balance the concentration of solutes inside and outside the cell. This loss of water can cause the bacteria to shrink and become dehydrated, potentially compromising their ability to survive and function properly.
How does triclosan kill bacteria?
Triclosan disrupts bacterial cell membranes and interferes with fatty acid synthesis, ultimately causing cell death. It can also inhibit the bacteria's ability to produce energy, leading to their destruction.
Does isopropyl alcohol effectively kill bacteria?
Yes, isopropyl alcohol is effective at killing bacteria by denaturing their proteins and disrupting their cell membranes.
Is the cell wall of gram positive bacteria thick or thin?
The cell wall of gram positive bacteria is thick.
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 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 thick outer layer of plant cell called?
The thick outer layer of a plant cell is called the cell wall... 8) A.I
Bacteria that produce thick walls around themselves are called?
Bacteria that produce thick walls around themselves are called Gram-positive bacteria. These bacteria have a thick peptidoglycan layer in their cell wall that retains the purple stain in the Gram staining technique. This thick wall provides structural support and protection to the bacterial cell.
What type bacteris that have a cell wall composed?
Bacteria with a cell wall composed of peptidoglycan are referred to as Gram-positive bacteria. These bacteria retain the crystal violet dye in the Gram staining process, giving them a purple color under a microscope. Examples include Staphylococcus and Streptococcus species.
What is cellouse cell wall?
Cell wall made out of cellulose is the cell wall of a plant. A fungi has a cell wall composed of chitin and a bacteria has a cell wall composed of glycoprotein.
What are the thick protein filaments in the cell made of?
The thick protein filaments in a cell are primarily made of a protein called myosin. Myosin filaments are involved in muscle contraction and various other cellular processes such as cell motility and cytokinesis.
Is Stratified squamous epithelium a thick membrane composed of several cell layers?
yes yes
What living things are composed of only one cell?
protists amoebas 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 are cell membranes and cell wall composed of?
The cell membrane and the cell wall is are composed of two different things. The cell membrane is made from phospholipid bilayers that becomes flexible by cholesterols. The cell wall is a rigid structure that surrounds the cell membrane that is either composed of cellulose, chitin, or peptidoglycan depending on the cell.
