Is it possible for a cell to survive in oxygen deficient condition?
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
In oxygen insufficient condition, an aerobic cell will not immediately die: it will generate some
Aerobic respiration refers to the cell's effort to break down glucose in an effort to make ATP with the presence of oxygen.
In Aerobic respiration, oxygen acts as the final electron acceptor for NADH and FADH2 to give up their electrons, forming NAD+ and FADH. This is required in both glycolysis, pyruvate oxidation and the Krebs cycle to function. Hence, no oxygen means that no electrons are transferred and thus NAD+ and FADH does not exist and these processes are unable to occur.
