In yeast, the products of anaerobic respiration (fermentation) are:

1. Ethanol (Alcohol): This is the primary product of alcoholic fermentation, which is a type of anaerobic respiration. Ethanol is commonly found in alcoholic beverages such as beer and wine.
2. Carbon Dioxide (CO₂): This gas is also a byproduct of alcoholic fermentation and is responsible for the carbonation in beverages and the leavening of bread dough.

The overall chemical reaction for alcoholic fermentation in yeast can be summarized as:

C6​H1​2O6​→2C2​H5​OH+2CO2​​

Here, glucose (C₆H₁₂O₆) is converted into ethanol (C₂H₅OH) and carbon dioxide (CO₂). This process occurs in the absence of oxygen and allows yeast to produce energy through fermentation.
