What would happen if the body does not receive enough oxygen for cellular respiration?

Answer 1

Cellular respiration cannot happen without oxygen. If there is no oxygen, only the glycolysis step will occur, and no ATP (energy) will be made, resulting in death. That is why humans die out in space; no oxygen is capable of being found, and cellular respiraiton cannot occur.

An organism lacking oxygen for cellular respiration would die, because oxygen is needed to make energy to live.

Answer 2

If the amount of oxygen in the atmosphere were to decline for some reason, we would all become more fatigued. People at higher altitudes would suffer more, and perhaps could not survive at those altitudes.

Another Answer

If there wasn't enough oxygen in the atmosphere, all land based living things that use oxygen (O2) to sustain life would suffocate. Amazing, isn't it? There are now 7 billion people on the planet, and that number is growing continually. We all consume oxygen and expel carbon dioxide. Green plants consume carbon dioxide and expel breathable oxygen, yet man is destroying the rain forest, the largest source of free oxygen. Irreversible damage. Man is the only creature that p***** upstream from where he drinks. Even bears know better. Man is a set of annoying zits on the face of this planet.

Answer 3

If there wasn't enough oxygen for aerobic respiration, only the glycolysis step would occur. The pyruvate would turn into lactic acid.

Answer 4

Women would finally stop complaining and get back in the kitchen where they belong.

Answer 5

The body either stops respiring for a while or dies, because it does not have enough O2 to function
