Fermentation is the process of deriving energy from the oxidation of organic compounds, such as carbohydrates, using an endogenous electron acceptor, which is usually an organic compound .
change in an organic substance caused by a ferment, such as souring of milk, with little or no oxygen involved, that is, anaerobic respiration

Alcohol fermentation is the formation of alcohol from sugar. Yeast, when under anaerobic conditions, convert glucose to pyruvic acid via the glycolysis pathways, then go one step farther, converting pyruvic acid into ethanol, a C-2 compound.
There is another way that the NADH molecule can be re-oxidized. Anaerobic conditions in yeast convert pyruvate to carbon dioxide and ethanol.

A catabolic process that makes a limited amount of ATP from glucose without an electron transport chain and that produces a characteristic end-product, such as ethyl alcohol or lactic acid.
fermentation A catabolic process that produces a characteristic product such as lactic acid or ethanol. Without an electron transport chain, fermentation makes a limited amount of ATP from glucose. See: respiration.

It's a whole process called . Sugars are broken down in an environment without oxygen. It's called anaerobic . And voila, alcohol. Even though they are single celled, you may find them in colonies.
Anaerobic respiration (both glycolysis and fermentation) takes place in the fluid portion of the cytoplasm whereas the bulk of the energy yield of aerobic respiration takes place in the mitochondria.
