उत्तर
Yeast is used in wine and beer industries because it respires anaerobically producing alcohol.
Explanation:
Yeast (fungi) respires anaerobically and yields ethyl alcohol and carbon dioxide. Due to the production of ethyl alcohol, yeasts are used in the brewing industry. This process of anaerobic respiration in yeasts is called fermentation.
