Answer: NAD+. Glycolysis requires a constant supplies of NAD+, which is used to produce NADH. In oxidative phosphorylation, the electron transfer chain will reduce the NADH to NAD+. Fermentation does the same task but in a slower fashion. NAD+ is essential for glycolysis.

How many NADH are produced during fermentation?

The fermentation pathway itself does not generate NADH itself. In fact NAD+ builds up. Glycolysis uses the NADH when oxidating carbon substrates and fermentation is used to regenerate the NAD+ and thus the cycle continues. If fermentation did not exist, NADH would build up and the cell would not be able to oxidize carbon anymore. The cell would die. In the case of respiration (aerobic or anaerobic) the cell will replenish its NAD+ pool the electron transport chain (oxidative phosphorylation). This generates even more potential to make ATP by pumping protons out of the cell using the energy generated from NADH -> NAD via NADH dehydrogenase. This gradient can be utilized by allowing the protons to flow back into the cell through ATPase, generating ATP. The utilization of NADH to pump protons out of the cell is the sole reason why respiration generates 36-38 ATP while fermentation generates 2 ATP per glucose. After much rambling, the point to take home is that the main job of fermentation in the cell is the replenish the NAD+ pool so that glycolysis can continue which drives biosynthesis.


Why do organism undergo fermentation?

The air around you - anywhere on earth - has lots of floating wild yeasts in it. A big jar of fruit juice left to the open air for a few days will start to ferment. Fermentation is the process where yeasts eat sugars, and, as waste product, create carbon dioxide - and alcohol. That is fermentation.


Can we stay in fermentation forever?

The process of fermentation releases carbon dioxide, so we can not stay in fermentation forever.

What is fermentation in cellular respiration?

Fermentation is a metabolic process that occurs in the absence of oxygen during cellular respiration. It involves the breakdown of glucose to produce ATP and end products such as lactic acid or ethanol. Fermentation helps cells to generate energy when oxygen is limited.


What happens to the lactic acid created during fermentation in human muscle cells?

During fermentation in human muscle cells, lactic acid is produced as a byproduct. This lactic acid is eventually broken down and converted back into energy by the body's cells, helping to replenish energy stores and reduce muscle fatigue.
