Final answer:

Alcohol fermentation is the process that produces ethanol using a two-step mechanism catalyzed by yeast enzymes.


Explanation:

Alcohol fermentation is the process that produces ethanol. It involves a two-step mechanism, with the first step releasing CO2 gas and acetaldehyde, and the second step oxidizing NADH to NAD+ and reducing acetaldehyde to ethanol.

Yeast enzymes catalyze the fermentation of sugars or starch from sources like potatoes, corn, wheat, rice, etc., to produce ethanol. This process is essential in various industries, including biofuel production and the making of alcoholic beverages.

In alcohol fermentation, the enzyme pyruvate decarboxylase removes a carboxyl group from pyruvate in the first reaction, while alcohol dehydrogenase transfers an electron from NADH to acetaldehyde in the second reaction, resulting in the production of ethanol.
