Detailed explanation-1: -Ethanol fermentation produces unharvested byproducts such as heat, carbon dioxide, food for livestock, water, methanol, fuels, fertilizer and alcohols.

Detailed explanation-2: -Alcoholic fermentation is a complex biochemical process during which yeasts convert sugars to ethanol, carbon dioxide, and other metabolic byproducts that contribute to the chemical composition and sensorial properties of the fermented foodstuffs.

Detailed explanation-3: -In plant and yeast cells pyruvate is converted into carbon dioxide and a type of alcohol called ethanol . This process is called fermentation and yields only two molecules of ATP per glucose molecule broken down.

Detailed explanation-4: -Fermentation reaction converts sugar molecules into alcohols or organic acids. Carbon dioxide is a byproduct of this reaction. When fermentation reaction occurs in food items like idly batter and bread dough, CO2 is released which makes the batters fluffy and soft.

Detailed explanation-5: -Products of Fermentation While there are a number of products from fermentation, the most common are ethanol, lactic acid, carbon dioxide, and hydrogen gas (H2). These products are used commercially in foods, vitamins, pharmaceuticals, or as industrial chemicals.
