Answer:
Fermentation
Explanation:
The diagram in the question is showing the process of alcohol fermentation, which produces ethyl alcohol or ethanol. In this process, a carboxyl group is removed from pyruvic acid and carbon dioxide gas is released. An electron is removed from NADH to form NAD+. In making alcoholic beverages, fermentation of pyruvic acid is carried out by yeast to produce the ethyl alcohol.
