Glucose. It can also use sucrose and maltose, but much less than glucose.

How long does a Sugar Yeast CO2 Generator produce CO2?
Carbon dioxide is the result of aerobic(oxygenated) respiration of yeast along with ethanol, as long as there is sugar and oxygen the yeast will produce CO2 but will cease if it is too hot/cold or if ethanol levels rise high enough to kill the yeast
What chemical substance do yeast consume?
Yeast uses sugar in respiration.Glucose is the primary substrate.This is oxidized during respiration
What are photosynthosis and cellular respiration a cycle in nature?
They are two different process one forms sugar and another utilize sugar to produce Energy. Photosynthesis is a process of producing sugar (glucose) from CO2+H2O,sunlight as a energy source (occurs in chloroplast). Cellular respiration (aerobic or anaerobic) provides energy (ATP) at the end of the cycle by using glucose and O2(aerobic-occurs in mitochondria) or without oxygen(muscle cells, yeast).
What is the difference between aerobic respiration and anaerbic respiration?
Aerobic respiration: 1) Requires oxygen 2) Occurs in the mitochondria 3) Produces 38 molecules of ATP 4) Products are carbon dioxide and water in both yeast and humans 5) The glucose molecule is completely oxidised. Anaerobic respiration: 1) Doesn't requires oxygen 2) Occurs in the cytoplasm 3) Produces 2 molecules of ATP 4) Products are lactic acid in humans and carbon dioxide and ethanol in yeast 5) The glucose molecule is partially oxidised.
What substances are produced in anaerobic respiration in plants and yeast?
oxygen-air we breath and gluecose-sugar in food
What is the purpose of adding yeast in aerobic respiration?
to get rid of sugars
Does yeast make carbon dioxide by aerobic respiration?
Yes

What determines whether yeast ferments or respires?
Yeast is a great example of Cellular Respiration. In a normal (Anaerobic) reaction, yeast breaks down sugar to release carbon dioxide and ethyl alcohol. When oxygen is added to the sugar and yeast, Aerobic respiration occurs. This releases more energy and less carbon dioxide than Anaerobic respiration. Of course, the reactions have to occur very close to 40 degrees Celsius or the yeast will die. If temperatures are too low, the reaction will not occur.
Difference between Aerobic and Anerobic Activity?
Aerobic : If respiration takes place in the presence of O2, then it is called aerobic respiration/ aerobic activity. Eg: Plants and animals, protozoans, some bacteriaAnaerobic: IF respiration takes place in the absence of O2, then it is called anaerobic respiration/ anaerobic activity. Eg: Yeast, some bacteria
Name 3 yeast behaviors based on modern concepts of microbial metabolism?
Three concepts of yeast behaviors are fermentation, aerobic or anaerobic respiration, and nitrification. Fermentation converts sugar to acids. Nitrification is the conversion of ammonia to nitrites.
What percentage of respiratory substrate is oxidised in aerobic respiration of glucose by yeast?
Between 65-70%
Why does yeast need to respire anaerobically?
in about 20-30 min.
What two types of yeast respiration is there?
Aerobic (used to make bread) and anaerobic (used to make alcohol).
What chemical substance do yeast consume?
Yeast uses sugar in respiration.Glucose is the primary substrate.This is oxidized during respiration

Differences between fermentation and respiration?
one uses oxygen to get energy and the other uses yeast!Fermentation does not need oxygen. Aerobic respiration need oxygen
