Can yeast produce CO2 with out sugar?
yeast is a living organism and every living organism needs energy, and yeasts energy comes from sugar.when the yeast respires the sugar it will cause the yeast to give off co2.
Why you add glucose to activate yeast cell?
Yeast can use glucose as their primary energy source.
Is there energy transformation in the rising of bread?
It is Chemical Energy because there are some chemicals stored on the bread which you eat.
What conditions is necessary for yeast to grow and multiply?
Yeast require energy to grow and divide its cells, therefore yeast grows best in sugar solution.

Why is yeast used to make beer and wine?
Yeast is used to produce the alcohol in beer and wine. Yeast is a fungus that feeds on sugars to create energy for itself. When the yeast is deprived of oxygen, as it is in the production of beer and wine, it uses a process called anaerobic respiration to create its energy. The byproducts of anaerobic respiration are ethanol (alcohol) and CO2. This production of alcohol via yeast is called fermentation. Yeast is used in the production of virtually all Alcoholic Beverages.
What purpose did sugar serve for the yeast?
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
Why is yeast a necessary ingredent in these foods and beverages?
to obtain energy
Which part of the yeast cell converts the nutrients the sugar into energy?
yyy
Why does yeast need to respire anaerobically?
in about 20-30 min.
When Cells use oxygen to release energy during?
Cells don't do fermentation, the yeast does. Cells don't do fermentation, the yeast does.
