Question

Is energy released during fermentation?

Answer 1

Fermentation:

1. Fermentation is an anaerobic process by which the breakdown of organic substances takes place by organisms to release energy.
2. Fermentation takes place inside the bacteria and in the muscle cells of the animals.
3. In fermentation, less than 7 percent of the energy present in glucose is released.
4. Energy is released in the process of fermentation but comparatively less than aerobic respiration.
5. In the microbes, during fermentation, such as yeast pyruvate (formed in the process of glycolysis) does not advance to the electron transport chain.
6. Rather, they generally accept hydrogen from NADH (a reduced form of NAD which is produced during glycolysis) leading to the production of carbon dioxide, ethanol, and oxidized NAD.
