NAD+, so glycolysis can continue. In alcoholic fermentation, which occurs in yeast, this is a two-step process. The first involves the Enzyme pyruvate decarboxylase (PDH). The pyruvate is decarboxylated to an acetaldehyde. This acetaldehyde then undergoes a reaction catalyzed by alcohol dehydrogenase to produce ethanol; this is the step in which the NAD+ is restored <ref>Garrett, R.H., & Grisham, C.M. (2007).
