<unk>  is the biological process by which sugars such as glucose, fructose, and sucrose, are converted into<unk>  and carbon dioxide. Yeasts carry out<unk>  on sugars in the absence of oxygen. Because the process does not require oxygen,<unk>  is classified as anaerobic.<unk>  is responsible for the rising of bread dough, the production of<unk>  in alcoholic beverages, and for much of the production of<unk>  for use as fuel.
