Question

Discuss the mechanism of alcoholic fermentation for producing beverages.

Answer 1

In alcoholic fermentation, the pyruvic acid from glycolysis loses one carbon in the form of carbon dioxide to form acetaldehyde, which is reduced to ethyl alcohol by NADH. When acetaldehyde is reduced to ethyl alcohol, Nadh becomes NAD+. This is fermentation that commonly occurs in yeast and is used for producing beverages.
