Why methylene blue can act on only dead yeast cells but not on live yeast cells?
Methylene blue can act on only dead yeast cells because it is able to penetrate the cell membrane easier when the cell is dead, allowing it to enter and stain the cell. In live yeast cells, the cell membrane is intact and acts as a barrier, preventing methylene blue from entering and staining the cell.
When living yeast cell were place in methylene blue they became blue why did this happen?
When you added methylene blue to the living yeast cell, the methylene blue is actually a dye so you could see the cells, therefore, the yeast cell became blue. It is much the same with hair dye. If you have a bottle of blue hair dye, it will dye your hair blue.
Why is methylene blue used as an indicator of cell respiration?
because methylene blue turns colourless when it is reduced by hydrogen. during respiration hydrogen is produced and instead of reducing NAD, it reduces methylene blue and turns methylene blue colourless. if methylene blue goes from blue to colourless then this shows that the cell is respiring as it is producing a suffiecient amount of hydrogen to decolourise methylene blue
Why is methylene blue necessary to view your check cells?
This is because the cheek cell is transparent. Since the membrane of the cheek cell is selectively permeable, it allows the methylene blue to enter the cell , therefore makes it blue in color from the inside. Then we are able to see the cheek cell properly under a microscope... please note. : we are supposed to add a bit of water and gliserene too . WATER : to transfer the cheek cells on to the slide AND GLISERENE: to prevent the cheek cells from drying up.
Why is methylene blue necessary?
Methylene blue is necessary for various applications, such as in medical diagnostics, staining biological tissues, and as a medication to treat methemoglobinemia. It is also used as a redox indicator in chemical reactions and as a dye in various industries. In microscopy, methylene blue can help highlight cell structures for better visualization.
How can methylene blue change the solute potential of the cell?
Methylene blue is a membrane-permeable dye that can enter the cell and bind to cellular components, such as proteins and nucleic acids. This binding can alter the osmotic properties of the cell and affect its solute potential. Methylene blue can also disrupt the electron transport chain in mitochondria, leading to changes in cellular metabolism and solute potential.
What is the behavior of methylene blue towards the animal charcoal?
i think the methylene blue will be make aqua blue because the charcoal will penerate the color of methylene blue,,,there are absorption process,,,in the charoal between the methylene blue.... (kharlz)

What does it mean if methylene blue ia blue?
If methylene blue is blue, it means that the compound is in its oxidized state (methylene blue) and has accepted electrons. Methylene blue can exist in both oxidized (blue) and reduced (colorless) forms depending on its redox state.
What color is simple staining on a bacillus and coccus using methylene blue stain?
Methylene blue stains everything blue.

Will potassium permanganate or methylene blue diffuse faster?
Methylene blue will diffuse faster than potassium permanganate. Methylene blue has a smaller molecular size and a higher diffusion rate compared to potassium permanganate.
Why is methylene blue is color blue?
Methylene blue appears blue because of its molecular structure, which allows it to absorb light in the red-orange range of the visible spectrum and reflect or transmit light in the blue range. This selective absorption and reflection of light wavelengths give methylene blue its distinctive blue color.
