Anaerobic respiration by yeast produces

The correct option is "All of the above".

Anaerobic respiration in yeast, also commonly known as fermentation, is a biological process where yeast breaks down sugars (like glucose) in the absence of oxygen to release energy. The chemical equation representing this process is:
$$C_6{H}_{12}{O}_6\to 2C_2{H}_{5}OH+2C{O}_2+\text{Energy}$$

Let's break down why all the given options are correct:
1. CO₂ (Carbon Dioxide): As shown in the chemical equation, carbon dioxide ($C{O}_2$) is directly produced as a byproduct of this reaction.
2. Alcohol (Ethanol): The reaction produces ethanol ($C_2{H}_{5}OH$), which is a type of alcohol.
3. Wine and Beer: Since yeast fermentation produces both alcohol and carbon dioxide, this exact biological process is industrially harnessed to brew alcoholic beverages like wine and beer.

Since anaerobic respiration by yeast produces carbon dioxide, alcohol, and is the foundational process for making wine and beer, all the individual options are correct. Therefore, the overall correct choice is "All of the above".
