Question

What are the two types of fermentation?

Answer 1

Fermentation:

1. The process of breakdown of organic compounds by organisms to release energy in the absence of oxygen.
2. The anaerobic breakdown of carbohydrates produces alcohol and carbon dioxide.
3. The anaerobic breakdown of carbohydrates in bacterial cells produces lactic acid.

The two types of fermentation are lactate and alcoholic fermentation.

Lactate fermentation:

1. The breakdown of starch and sugar into lactic acid by yeast strains and bacteria.
2. While doing heavy exercises, the energy consumption becomes faster than the oxygen supplied to muscle cells, this leads to the accumulation of lactic acid and muscle pain.

Alcoholic fermentation:

1. It is also termed ethanol fermentation, which involves converting pyruvate to acetaldehyde and CO₂.
2. The final product of glycolysis, pyruvic acid, is broken down into alcohol and carbon dioxide.
3. To make Wines and beers, alcoholic fermentation is used.
