What are the ingredients of fermentation?

Flexi Says:
You are probably most familiar with the term fermentation in terms of alcoholic beverages. You may not have considered that the process is actually a chemical reaction certain bacteria and yeasts use to make ATP. Like lactic acid fermentation, alcoholic fermentation, which is also referred to ethanol fermentation, processes pyruvate one step further in order to regenerate NAD+ so that glycolysis can continue to make ATP, even in low oxygen environments. In this form of anaerobic respiration, pyruvate is broken down into ethyl alcohol (C2H6O) and carbon dioxide.
