When yeast cells are used in making bread rise, they get energy from the sugar mixed within the bread dough. When oxygen is present, these single celled fungi perform cellular respiration. When there is no oxygen they perform fermentation. By performing fermentation they produce carbon dioxide gas (which causes the bread to rise) and energy storing molecules called ATP. By fermentation they produce more and more ATP. More and more energy.

Process used by yeast?
Yeast cells undergo cellular respiration. Yeast cells need oxygen to complete the first stage of the cell cycle, so they must first undergo cellular respiration.
What cells does alcohol affect?
Yeast produces both in Alcohol Fermentation
Yeast cells under anaerobic conditions?
Yeast cells are facultatively anaerobic. This means that they perform fermentation under anaerobic conditions. When the oxygen concentration is low, pyruvate is turned into ethanol and carbon dioxide.
What type of organisms use alcoholic fermentation?
Yeast
What fermentation includes ethyl alcohol?
Alcoholic fermentation
Yeast cells perform what kind of fermentation?
Bread. Without it, the bread would never rise.
What do yeast make during fermentation?
Yeast fermentation is a digestive process that it used to perform growth and reproduction. Fermentation is a form of metabolism by yeast.
When Cells use oxygen to release energy during?
Cells don't do fermentation, the yeast does. Cells don't do fermentation, the yeast does.
Process used by yeast?

Yeast cells produce alcohol and carbon dioxide in the process of what?
Fermentation.
What is one product in fermentation in yeast cells?
carbon dioxide and ethanol
Yeast cells carry out fermentation when they are supplied with what type of molecule?
sugar
What organisms can ferment lactose?
some prokaryotes mammalian muscle cells yeast
What is the chemical action of yeast on sugars called?
Yeast act on sugars in the process of fermentation .
What are cells that perform fermation and make alcohol are?
yeast cells
What cells does alcohol affect?
Yeast produces both in Alcohol Fermentation
What do this mean yeast is facultative anaerobe?
means that they perform fermentation only under anerobic conditions
