Solution

Fermentation:Fermentation is the metabolic process through which a microorganism transforms a carbohydrate such as starch or sugar into an alcohol or acid.Yeast, for example, ferments sugar into alcohol to obtain energy.Ethanol fermentation is a process in which pyruvate (a byproduct of glucose metabolism) is broken down into ethanol and carbon dioxide by yeast and bacteria. $\underset{\mathrm{Glucose}}{{\mathrm{C}}_{6}{\mathrm{H}}_{12}{\mathrm{O}}_{6}\left(\mathrm{aq}\right)}\to \underset{\mathrm{Ethanol}}{2{\mathrm{C}}_{2}{\mathrm{H}}_{5}\mathrm{OH}\left(\mathrm{l}\right)}+\underset{\mathrm{Carbon}\mathrm{dioxide}}{2{\mathrm{CO}}_{2}\left(\mathrm{g}\right)}$Many more alcohols can be generated in this way, but synthetic ways are more likely used.Therefore, alcohol is produced with the help of fermentation.
