If your cells (human/animal) are temporarily in oxygen debt (rest of question in details)?

Question

If your cells (human and animals) are temporarily in oxygen debt, they will perform lactic acid fermentation in place of aerobic respiration---why?

Answer 1

Lactic acid is a byproduct of anarobic respiration. This lactic acid is what causes muscle fatigue and sore muscles. Lactic acid must be transported to the liver where it is then transformed, in the presence of oxygen, back to glucose. The oxygen needed to perform this function is what we call "oxygen debt". It is the "price we pay" to "get rid of" the lactic acid and make it more useful..

Answer 2

You need oxygen in order to produce ATP through the mitochonndria. So if there is oxygen debt, the intermediates of the Krebs cycle build up and the only way to make ATP is through (1) glycolysis, (2) lactic acid fermentation, mostly in skeletal muscles and (3) lipid metabolism to form ketone bodies, but that usually takes days to swing into full gear.

Answer 3

if oxygen is not present during glycolysis, then the cells will undergo lactic acid fermentation as opposed to the Kreb's cycle

aerobic respiration is with oxygen and anaerobic respiration is without oxygen

oxygen is the final electron receptor in the electron transport system (the last step in the cell cycle)

Answer 4

because aerobic respiration requires oxidative phosphorealtion which means it can only happen with oxygen. Oxygen is a very high electron affinity and acts as an electron acceptor in the mitochondria during that process.
