Why does yeast respiration happen?
Inside yeast. They are facultative anaerobes.They can breath aerobically or anaerobically. So it takes place in cytoplasm and mitochandria
Do yeast cells move by themselves?
Yeast are simple fungi. The term "yeast" refers more to a life-style than to a phylogenetic classification. Yeast cells don't really move on their own, but they do multiply by budding. That is why bread needs to be kneaded. It helps spread the yeast cells throughout the whole loaf. Yeast cells don't have to be motile to contact each other. They move passively by means of "currents" in the water caused by temperature differences and random thermal motion (diffusion).
How many types yeast are there?

What organisms use alchoholic fermentation?
Yeast and Bacteria. :)
What type of organisms use alcoholic fermentation?
Yeast
How can i prove that yeast is alive?
Place the yeast in warm, sugary water. Eventually, the yeast cells will begin to divide and increase. Bubbles of carbon dioxide and alcohol is given off.
Are grains of yeast alive?
yes, yeast is still alive because it is a living thing
What is more alive yeast salt or sugar or flour?
Yeast is a living organism. Salt, sugar and flour are compounds that are not alive.
Is yeast alive because it takes in oxygen and releases carbon dioxide?
Yeast cells are alive. However, it takes in oxygen in the form of glucose. yeast + glucose -> alcohol + CO2 We know that yeast cells are alive because it produces wastes (alcohol and carbon dioxide) and they reproduce.
Is yest alive?
yes yeast is alive when u add hot water
Is a yeast cake living or non living?
Yes, yeast is alive it eats sugars, it grows, it reproduces.
What happen to dough if you put yeast to it?
I'm pretty sure its the yeast that makes it rise. did you know that yeast is actually a living organism? its alive.
What is the purpose of yeast plus water in a sugar and yeast experiment?
i had the same exact question for my science report determining wether or not yeast cells are alive.
Where was yeast originated in?
yeast is its own organism, it's alive itself, that's why it works in bread and beer and stuff.
What conditions does yeast need to be in to survive?
As a living organism yeast needs sugars, water and warmth to stay alive.
How long can you let active dry yeast prove?
About 20 mins is fine.
What conditions do yeast need to be alive?
Carbohydrates for fermentation and optimum temperature
