In making bread - Bread dough contains yeast (a fungus), and sugar.
When the dough is left in a warm place, the yeast cells feed on the sugar to obtain energy. Enzymes in the yeast catalyse the reaction, which is called fermentation:
C6H12O6 (aq) ------> 2C2H5OH (aq) + 2CO2 (g) + energy
in other words:
Glucose ------> ethanol + carbon dioxide + energy

What is achoholic fermintaition?
Alcohol is produced as a byproduct of live yeast. The yeast digests the sugar from the mash and excretes alcohol. The process is called 'Fermentation'
Does salt and yeast inflate a balloon?
Live yeast can be used to inflate a balloon if you give the yeast something to ferment (such as sugar). They then produce carbon dioxide as a waste product that could inflate a balloon. You should not expect it to be buoyant, however, for CO2 is heavy as gases go (considerably heavier than air, for instance). The yeast cannot use salt for much of anything, however.
What is the control in a bread mold experiment?
The bottle that contains only yeast and water. The experimental group in the bottle with yeast, water, AND sugar.
How can i explain the process of fermentation?
Fermentation is a process that converts sugar to acids, gases or alcohol. In yeast the fermentation process is carried our in beers, wines and other alcohol.
What does yeast need to work?
Yeast needs water, food (in the form of sugar) and heat to grow. It does not need oxygen and can grow quite well under anaerobic conditions. The presence of oxygen during fermentation can actually favor the growth of other microorganisms that will compete with the yeast.
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.
What purpose does vascular tissue serve in trees?
Movement of water and solutes such as sugar.
Sugar and yeast?
There is no sugar in yeast because it is a living organism and living organisms don't need sugar.
What does sugar do to yeast?
Yeast will respire the sugar causing the yeast to give off Carbon Dioxide.
Does alcohal have yeast in it?
No, alcohol does not have yeast in it; it is produced by yeast from sugar.
What role does sugar play in mixing with yeast?
yeast only feeds on things with a sugar ingredent so, sugar feeds yeast, cause it grow.
Why do we use sugar in yeast?
the sugar has power over fermentation. fermentation can not continue without sugar or yeast
Does yeast eat sugar?
No, sugar is NOT necessary when making yeast bread. Yeast has enough simple sugars in flour to grow and multiply. makebread.com.au
Why does a sugar solution become alcoholic on adding yeast?
Yeast consumes sugar and as a byproduct you get alcohol. In simple terms, yeast eats sugar and pees out alcohol.
Does yeast grow faster or slower with more sugar?
Yeast is a bacteria that feeds on sugar, which causes the fermentation process. In the process of wine making, grapes have yeast in the skin and sugar in the flesh of the fruit, the yeast then feeds on the sugar in the flesh fermenting the juice and making the wine.
Why does sugar make yeast rise faster?
Yeast is made up of microorganisms (fungi) that feed on starches and sugar, producing gas that makes dough rise. Yeast can digest sugar quicker than starches, so rises faster when sugar is included.
