Answer:
Unlike lactic acid fermentation where-in the end product is lactic acid, the 'waste' material in an alcohol respiration is ethanol (an alcohol) and CO2 (carbon dioxide).

Step-by-step explanation:
In alcoholic fermentation, pyruvate changes to alcohol and carbon dioxide. This type of fermentation is carried out by yeasts and some bacteria.
