Does Fermentation Require an Organic Electron Acceptor?

Fermentation uses an organic molecule as a final electron acceptor to regenerate NAD⁺ from NADH so that glycolysis can continue. Fermentation does not involve an electron transport system, and no ATP is made by the fermentation process directly.

What is the electron acceptor in fermentation?

Under normal aerobic conditions, the final electron acceptor at the end of the electron transport chain is oxygen. ... In lactic acid fermentation, NADH is the electron carrier that ultimately carries them to pyruvate. Pyruvate is reduced to lactic acid, and thus, acted as the final electron acceptor.

Does fermentation require organic molecules?

Fermentation includes processes that use an organic molecule to regenerate NAD⁺ from NADH. Types of fermentation include lactic acid fermentation and alcohol fermentation, in which ethanol is produced.
