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.
Is yeast living or dead or nonliving?
Yeast is a living organism in the fungal kingdom. It is a single-celled organism that can reproduce and metabolize nutrients.
Can dead yeast respire?
No, dead yeast cannot respire because respiration is a metabolic process that requires living cells to produce energy. Once yeast cells die, they are no longer capable of carrying out cellular activities like respiration.
Is saccharomyces cerevisiae harmful?
Saccharomyces cerevisiae, also known as baker's yeast, is not harmful to humans in small amounts and is commonly used in baking and brewing. However, consuming large amounts of it could potentially lead to digestive issues for some individuals.
What happens when you mix glycogen plus yeast?
if we put yeast in sugar water , yeast is a single-celled organism, so it will multiply fast and grow to more cells
What is the difference in appreance between boiled and unboiled yeast cells in Congo red solution?
since the unboiled yeast is alive it will not allow the congo red to be absorbed and the boiled yeast is dead so it doesnt have any way to fight of the solution(congo red)
Can boiled beans grow?
No, the seeds wll be dead

Why is Vegemite a concentrated solution?
Vegemite is the left overs after the beer is brewed. It's a concentrated mix of dead yeast and a little bit of liquid that is boiled off to make the paste. It's not really a solution as the yeasts do not actually dissolve. Vegemite is a product brand name for Autolysed yeast paste. Marmite is another brand name for this paste. Autolysis means the yeast began feeding on itself, converting their cellular structures into multiple glutamic compounds. These are where it gets it's characteristic salty taste.
Is yeast living or dead or nonliving?
Yeast is a living organism in the fungal kingdom. It is a single-celled organism that can reproduce and metabolize nutrients.
What can you use old dry active yeast besides baking?
Old yeast, depending on how old, is probably dead and will not be good for using in anything. When in doubt, throw it out.
Is it ok to eat expired yeast?
If you are using the yeast in bread, then if it is expired it may be dead and your bread will not rise. You could make a sponge of the yeast by mixing it with warm (not hot) water and wheat flour; if the sponge becomes foamy, your yeast is fine to use. If you are eating it as a dietary supplement it depends on the form. If it is in a dry form, it probably is okay if it is slightly expired. If it is in a wet form, if the yeast is dead then harmful organisms may replace it and it should probably be discarded.
Can you die from yeast infection?
no you cant . if you could half of the women in the world would be dead
My quick rise yeast's packet said best if used by November 2008 is it still okay to use for pizza dough?
Put a little of the yeast in a glass of warm water. If you see tiny bubbles, the yeast is still good. If not, adding the dead yeast will not make the dough rise.
Was glue made of dead horses once?
It was once made of boiled and melted hooves and similar parts.
Can dead yeast respire?
No, dead yeast cannot respire because respiration is a metabolic process that requires living cells to produce energy. Once yeast cells die, they are no longer capable of carrying out cellular activities like respiration.
What happens when yeast is added to methylene blue?
When yeast is added to methylene blue, the dye is taken up by the yeast cells, which can be observed under a microscope. In the presence of live yeast, the methylene blue is reduced and loses its color, indicating metabolic activity. However, if the yeast is dead or inactive, the dye remains blue, demonstrating the yeast's ability to reduce the dye through cellular respiration. This experiment is often used to illustrate the concept of cellular metabolism and the viability of yeast cells.
