Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Alcoholic fermentation occurs in which of the following?
A
bread dough.
B
any environment containing oxygen.
C
muscle cells.
D
mitochondria
Explanation: 

Detailed explanation-1: -Yeasts in bread dough use alcoholic fermentation and produce carbon dioxide gas. The gas forms bubbles in the dough, which cause the dough to expand.

Detailed explanation-2: -In the absence of oxygen, alcoholic fermentation occurs in the cytosol of yeast (Sablayrolles, 2009; Stanbury et al., 2013). Alcoholic fermentation begins with the breakdown of sugars by yeasts to form pyruvate molecules, which is also known as glycolysis.

Detailed explanation-3: -In a bread dough, oxygen supply is limited and the yeast can only achieve partial fermentation and instead of carbon dioxide and water being given off, carbon dioxide and alcohol are produced. This is called alcoholic fermentation.

Detailed explanation-4: -Alcoholic fermentation is the process of using yeasts to convert sugars into alcohol. Distillation is a process used to higher-ABV beverages from already-fermented base products. (For example, the distillation of beer wort creates whiskey, while the distillation of wine produces brandy.)

Detailed explanation-5: -Alcoholic fermentation Examples: Wine, Beer, Cidre, Met, Bread.
