Lactic acid which may cause fatigue if in muscles .
The two substances that may be formed in anaerobic respiration are lactic acid and ethanol. Lactic acid is produced in the muscles during strenuous exercise, while ethanol is produced by yeast during fermentation.
Short Answer: To regenerate NAD+ for the continued function of glycolysis.Detailed Answer: As NADH is formed in glycolysis (2 NADH per glucose), NAD+ must be regenerated to allow continued glycolytic flux (and consequent production of ATP). In the presence of adequate oxygen (i.e. under aerobic conditions), this regeneration takes place predominantly in the mitochondria. Under anaerobic conditions, however, the only way to regenerate NAD+ is through lactate fermentation (e.g. mammals) or ethanol fermentation (e.g. yeast).
Respiration: the physical and chemical processes by which an organism supplies its cells and tissues with the oxygen needed for metabolism and relieves them of the carbon dioxide formed in energy-producing reactions. Fermentation: an enzymatically controlled anaerobic breakdown of an energy-rich compound (as a carbohydrate to carbon dioxide and alcohol or to an organic acid). Both definitions were obtained from the Merriam-Webster website.
In both, ATP is produced. In Fermentation, each turn of the cycle produces 2 ATP, and in Aerobic Cellular Respiration, each turn of the cycle produces 38 ATP. You can see which one works better...the huge difference in the number of ATP produced.
The reactions of anaerobic respiration take place in the cytoplasm.
The two substances that may be formed in anaerobic respiration are lactic acid and ethanol. Lactic acid is produced in the muscles during strenuous exercise, while ethanol is produced by yeast during fermentation.
Nopes. Lactic acid is formed during anaerobic respiration in humans and other animals. Alcoholic fermentation is carried out by yeast, and produces ethanol.
During fermentation, particularly in the process of alcoholic fermentation, sugars are converted into ethyl alcohol (ethanol) and carbon dioxide by microorganisms, primarily yeast. This biochemical process occurs under anaerobic conditions, meaning it happens without oxygen. The ethanol produced is commonly found in alcoholic beverages, while the carbon dioxide can be released as a gas or used in carbonation. Additionally, fermentation can also produce various other byproducts, such as organic acids and flavor compounds, depending on the substrate and microorganisms involved.
During fermentation, three possible products that can be formed are alcohol (such as ethanol), carbon dioxide, and organic acids (like lactic acid or acetic acid). The specific products depend on the type of fermentation process and the microorganisms involved. For instance, yeast typically produces alcohol and carbon dioxide during alcoholic fermentation, while lactic acid bacteria produce lactic acid during lactic fermentation.

Plants produce ethanol at the end of anaerobic respiration, also known as fermentation. This process helps plants generate energy in the absence of oxygen by breaking down sugars into ethanol and carbon dioxide.
lactic acid is formed by anaerobic respiration when insufficient oxygen is present.
starch is formed by fermentation.
Lactic acid is the chemical substance formed during anaerobic respiration in muscles when there is not enough oxygen available to meet energy demands.
Muscle cells produce lactic acid during anaerobic fermentation. A buildup of lactic acid cause your muscles to feel tired.
It always produces NAD+ out of NADH, because that's the main reason why micro-organisms ferment. Besides that, the other products that are being formed depend on which type of fermentation, although you could say that an acid is always formed as well (but depending on the type, the amount of acid might be very small).
