What happens in alcoholic fermenatation?

During alcoholic fermentation:

Glucose (a sugar) is broken down by yeast

2 pyruvate molecules are formed through glycolysis

Pyruvate is converted into acetaldehyde

Acetaldehyde is reduced to ethanol

Carbon dioxide is also released as a byproduct

The chemical equation for alcoholic fermentation is:

C₆H₁₂O₆ → 2 C₂H₅OH + 2 CO₂

The overall reaction is exergonic, meaning it releases energy in the form of heat. This energy is used by yeast to grow and reproduce.

Alcoholic fermentation is a crucial process in the production of alcoholic beverages, such as beer, wine, and distilled spirits. It is also used in the production of some foods, such as bread, cheese, and yogurt.
