Final answer:
During alcoholic fermentation, carbon dioxide gas is given off.
Step-by-step explanation:
During alcoholic fermentation, carbon dioxide gas is given off.
Alcoholic fermentation is a process carried out by yeast and some bacteria, where glucose is broken down into ethanol and carbon dioxide. This process is used in the production of alcoholic beverages like wine and beer, as well as in other applications like bread-making.
For example, when yeast ferment grape juice to make wine, the carbon dioxide produced during fermentation is released and creates bubbles in the wine, giving it its characteristic fizziness.
