Is it possible for a cell to survive in oxygen deficient condition?

Answer 1

Aerobic respiration refers to the cell's effort to break down glucose in an effort to make ATP with the presence of oxygen.

Because oxygen is the last electron acceptor that NADH and FADH2 need to give up their electrons in order to form NAD+ and FADH, it is essential to aerobic respiration. Without oxygen, electrons cannot be transferred, which prevents NAD+ and FADH from existing and prevents pyruvate oxidation, the Krebs cycle, and glycolysis from occurring.

Please note that cellular respiration does not always mean oxygen dependent aerobic respiration, as cells may also perform anaerobic respiration.

There are cells which generate #"ATP"# without using oxygen such as anaerobic bacteria of gut or red blood cells of our blood.

In oxygen insufficient condition, an aerobic cell will not immediately die: it will generate some #"ATP"# through anaerobic respiration and survive. In that case, accumulation of unusual wastes in cell causes toxicity. The condition could be reversed if oxygen is supplied to the system as soon as possible.

Yes, some cells can survive in oxygen-deficient conditions through anaerobic respiration or fermentation.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
