During fermentation , yeast break down pyruvate into ethanol and Nicotinamide adenine dinucleotide(NADH) is
regenerated to keep glycolysis running and producing a small amount of ATP.
<h3>What is fermentation?</h3>
Fermentation is the process whereby glucose or carbohydrates are break down into alcohol in the presence of an enzymes or yeast. and in the absence of oxygen. Two molecules is involved in fermentation.
Therefore, During fermentation , yeast break down pyruvate into ethanol and Nicotinamide adenine dinucleotide(NADH) is regenerated to keep glycolysis running and producing a small amount of ATP
