Which organism is responsible for alcohol fermentation? (1) Chlorella (2) Yeast (3) Agaricus (4) Puccinia
by

1 Answer

Answer :

(2) Yeast Explanation: Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as a side-effect. It is an anaerobic process since Yeasts perform this conversion in the absence of oxygen.
