Question
Yeast is used in wine and beer industries because it respires
Options
aerobically producing oxygen
aerobically producing alcohol.
anaerobically producing alcohol.
anaerobically producing CO2.
Solution
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.
