The MAIN FUNCTION OF FERMENTATION is to regenerate the coenzyme NAD+, so that the glycolysis process can continue to breakdown glucose, produce ATP, and also produce pyruvate for the continuation of the process at the same time in anaerobic conditions when no oxygen is available.
Accordingly, what is the process of fermentation?
Fermentation is a metabolic process that consumes sugar in the absence of oxygen. The products are organic acids, gases, or alcohol. It occurs in yeast and bacteria, and also in oxygen-starved muscle cells, as in the case of lactic acid fermentation. The science of fermentation is known as zymology.
How does fermentation produce ATP?
The net energy gain in fermentation is 2 ATP molecules/glucose molecule. In both lactic acid and alcoholic fermentation, all the NADH produced in glycolysis is consumed in fermentation, so there is no net NADH production, and no NADH to enter the ETC and form more ATP.
What are the product of fermentation?
The end products of fermentation are alcohol, carbon dioxide and lactic acid. The process is essential in the production of beer, fermented milk and bread. To arrive at these end products, sugars are broken down in a process called glycolysis.
