Ethanol Fermentations - In alcoholic fermentation, pyruvate is first activated, and is then converted by pyruvate decarboxylase into acetaldehyde and CO2. Acetaldehyde is then reduced to ethanol in a NAD linked reaction involving alcohol dehydrogenase. This fermentation is a major pathway in some yeasts but is not important in bacteria.
