Re: Oxygen level required for a single cell (neuron)

I will give you the direction to solve the problem. The answer which you will 
get is probably quite a good approximation. 

Adult respiratory rate 18 to 20 times per minute. Tidal volume is 500 mL.
Hence, you can assume that the amont of air available for exchange is around 10 
litres per minute, of which 20% is oxygen (i.e. 2 litres per minute of which 20% 
is consumed by our central nervous system).  Now find out how many neurons are  
in our Central Nervous System, and you will get the approximate oxygen 
consumption for an individual neuron.
Hope this will help.
