Question

What type of fermentation occurs in yeast?

Answer 1

The type of fermentation that occurs in yeast is alcoholic fermentation, where glucose is converted to ethanol and carbon dioxide, especially used in making bread, wine, and beer.

Step-by-step explanation:

The type of fermentation that occurs in yeast is called alcoholic fermentation. This biochemical process happens in the absence of oxygen and converts sugars such as glucose into ethanol (CH3CH2OH) and carbon dioxide (CO2). The general balanced chemical equation for the fermentation of glucose by yeast is:

C6H12O6 → 2 C2H5OH + 2 CO2

Alcoholic fermentation is utilized for various purposes, such as in the production of bread, wine, beer, and biofuels. In the context of bread making, the produced carbon dioxide allows dough to rise. In wine and beer production, the sugars in grapes or grains are converted to alcohol and carbon dioxide. Significant in history, alcoholic fermentation and the use of Saccharomyces cerevisiae, also known as brewer's or baker's yeast, has been integral to these processes.

Answer 2

Alcoholic fermentation, otherwise known as ethanol fermentation, is an anaerobic process that drives the release of cellular energy by converting biological fuels, such as sugars, into ethanol and carbon dioxide. The microorganisms that carry out alcoholic fermentation are unicellular eukaryotic fungi called yeasts so this would be your answer.
