What molecule is produced with the expenditure of nadh fermentation?
Lactate is produced in this way. It is a product of the NADH fermentation.
What is the euqation for lactic acid fermentation after glycolysis?
Pyruvate+NADH--->Lactate + NAD+ +ATP
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.
What does fermentation replenish?
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.
What is the equation for alcoholic fermentation after glycolysis?
The product of glycolysis is pyruvate. In alcoholic (ethanol) fermentation, pyruvate is converted into ethanol and carbon dioxide. The first step is decarboxylation, catalyzed by pyruvate decarboxylase: CH3COCOO- --> CH3CHO pyruvate --> acetaldehyde Then acetaldehyde is reduced to ethanol; this step is catalyzed by alcohol dehydrogenase and involves the oxidation of NADH+ + H+ to NADH: CH3CHO --> CH3CH2OH
What molecule is produced with the expenditure of nadh fermentation?
Lactate is produced in this way. It is a product of the NADH fermentation.
Why is NADH such a integral part of Glycolysis and Fermentation?
because it is
The main purpose of reduction of pyruvate to lactate during fermentation is to?
Alcoholic fermentation occurs in organisms such as yeast, as produces ethyl alcohol. Lactic acid fermentation occurs in animals such as humans and produces lactic acid instead of alcohol.
What are reactants in fermentation?
In animals, fermentation is referred to as lactic acid fermentation. Its reactants include a sugar molecule, pyruvate and NADH. It produces lactic acid and releases energy.

What is the euqation for lactic acid fermentation after glycolysis?
Pyruvate+NADH--->Lactate + NAD+ +ATP
What occurs during fermentation?
Decrease in NADH, pyruvate is broken down into carbon dioxide and acetylaldehyde, NADH is oxidized to NAD+, and acetylaldehyde is reduced to make ethanol.
How does the process of fermentation allow the survival of yeast?
Fermentation allows yeast to survive in an anaerobic environment without suffering the NAD+/NADH imbalance and lactate acidosis associated with regular anaerobic respiration. Excess NADH is shunted to produce ethanol from pyruvate, reducing NADH levels, replenishing NAD+ levels, and preventing the formation of acidic lactic acid.
What is 6 products made by fermentation?
All fermentation produces ATP and 2 pyruvate. Alcohol fermentation will also produce Acetaldehyde and thereby Ethanol. Lactic acid fermentation produces Lactate. In the process of fermentation NADH (aka reduced NAD) is also produced.
Describe the role of fermentation in the second stage of cellular respiration?
It frees up NADH to be used in glycolysis again.
