Detailed explanation-1: -This type of fermentation is carried out by yeasts and some bacteria. It is used to make bread, wine, and biofuels. Alcoholic fermentation produces ethanol and NAD+. The NAD+ allows glycolysis to continue making ATP.
Detailed explanation-2: -Alcoholic fermentation is carried out by yeasts and some other fungi and bacteria. The first step of the alcoholic fermentation pathway involves pyruvate, which is formed by yeast via the EMP pathway, while it is obtained through the ED pathway in the case of Zymomonas (bacteria).
Detailed explanation-3: -Human cells cannot carry out alcoholic fermentation, yet we use it for many purposes.
Detailed explanation-4: -Alcohol fermentation is found in some bacteria and in humans. The two pyruvate molecules formed during glycolysis result in two Krebs cycles. Electron transport is the first step in the breakdown of glucose.
