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.

How many ATP molecule are produced during fermentation?
2
What are the output of energy in cellular respiration?
During cellular respiration a molecule called Adenine triphosphate or ATP is produced which is used for many different aspects of a cell's functions. Another molecule that is produced that contains potential energy is called NADH. A net total of 2 ATP and 2 NADH is produced during the stages of cellular respiration known as glycolysis and linkage reactions.
How many total molecule of carbon dioxide are produced during lactic acid fermentation of 1 glucose molecule?
2
How many moles of ATP are produced from each mole of NADH and FAD in the ETS?
Electron Transport Phosphorylation(chemiosmosi) produces 32 ATPs
How many ATP molecules are formed for each fadh2 and nadh?
FADH2 allows for the formation of 2 molecules of ATP during the Kreb's cycle.
How many ATP molecule are produced during fermentation?
2
How many NADH molecules are produced during the stages of aerobic respiration?
10 NADH molecules are produced in total. 2 during glycolysis, 2 during link reaction (1 per pyruvate, 2 per glucose molecule), and 6 during the Krebs cycle. None during the electron transport chain.
How many net molecules of ATP are produced during glycosis?
Glycolysis produces 4 ATP's and 2 NADH, but uses 2 ATP's in the process for a net of 2 ATP and 2 NADH
How many NADH molecules are produced in glycolysis?
There are 2 net ATP produced during glycolysis. 4 are produced but 2 are used so the net production is 2. There are 2 NADH produced which are then transferred to to the electron transport chain.
