Detailed Solution

Concept- Yeast uses fermentation as a kind of anaerobic respiration.
A metabolic process called fermentation is one in which energy is produced from carbohydrates without the presence of oxygen.
Alcohol is created when yeast ferments sugar.
Glycolysis is the process by which yeast breaks down carbohydrates to produce pyruvate molecules.
Ethyl alcohol and carbon dioxide are the byproducts of yeast's anaerobic respiration. Using fermentation, anaerobically produced ATP is made.
The end products produced by the yeasts, ethanol and carbon dioxide, can be employed in the processing of food.
Hence, the correct answer is option 3 - Ethanol.
