Detailed explanation-1: -Fermentation is the natural process in which sugars are converted to alcohol by yeast. Carbon dioxide is also released in this reaction as a byproduct. This process is used in distilleries (alcohol industries) for the production of wine, beer and spirits.
Detailed explanation-2: -In the process, yeasts break molecules of pyruvate, leading to the metabolism of glucose referred to as glycolysis into sugars or starch down to molecules of carbon dioxide and alcohol. Alcoholic fermentation produces beer and wine.
Detailed explanation-3: -When yeasts eat sugar and turn it into energy, they also produce carbon dioxide. This process is known as fermentation. In this activity, the balloons on the bottles should have captured carbon dioxide produced by the yeasts during fermentation.
