questions about respiration

[Bonnie Polan]

Look up in your text the chapter on cell respiration.  This is the 
energy releasing pathway which breaks down primarily glucose to 
release energy in the form of ATP.  Breathing allows the body to take 
in oxygen from the air.  This oxygen is necessary for cell 
respiration to take place.  When one molecule of glucose is broken 
down in the presence of oxygen, 36 mol. of ATP are generated.  
Without oxygen, only 2 ATP's are generated.  Good luck with biology.
