How is ethanol prepared by the fermentation process?
Fermentation is a biological mechanism that uses no oxygen to obtain energy from carbohydrates.
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.
Ethanol () is produced by the enzymes invertase and zymase fermenting sugar.
For the production of ethanol from glucose, the net chemical equation is:
