what purpose is served by the formation of lactic acid during anaerobic respiration?

Question

AND how is this accomplished during aerobic respiration

Answer 1

Lactic acid fermentation happens when oxygen is not available. Fermentation follows glycolysis. Glycolysis gives a net gain of 2 ATP which isn't much but is better than nothing. However, glycolysis cannot continue unless NADH+ is available to pick up the electrons that are removed from the glucose. In ordinary aerobic respiration, the NADH+ would carry the electrons to the electron transport chain.

But without oxygen the NADH+ cannot give up electrons to the electron transport chain because the electron transport chain doesn't work without oxygen. It's "out of order". So the muscle cells change the pyruvate molecules from glycolysis into lactic acid and free up the NADH+ to return to the glycolysis reactions to get more electrons. This keeps glycolysis going. Without the fermentation, glycolysis would stop because no NADH+ would be available.

Answer 3

Lactic Acid Formation

Answer 4

In the production of energy(ATP)Adenosine Tri-Phosphate, there are 2 ways for the body to achieve this and thats through aerobic respiration or anaerobic respiration.
In aerobic respiration: your body would need Glucose+ oxygen to produce energy and in turn would release CO2 & H2O
formula: Glucose(C6H12O6) + Oxygen = Carbon Dioxide + Water + Energy
In anaerobic respiration: your body compensates for the lack of Oxygen and only uses glucose to produce energy. this would result in the formation of lactic acid
formula: glucose=lactic acid + 2ATP(energy)
C6H12O6 = 2C3H6O3 + 2 ATP

i hope this is sufficient to answer your question :)

Answer 5

lactic acid is involved in aerobic respiration because in the formula there is oxygen and aerobic respiration you use oxygen. Also humans produce lactic acid and humans do aerobic respiration

Answer 6

when your body doesnt have enough oxygen it is formed as a byproduct of anaerobic respiration.


it serves no purpose other than as a waste product.
