The food we eat undergoes series of complex digestion stages until it's finally converted into Glucose; the the Mitochondrions in the brain cells react oxygen with glucose to obtain the body fuel which is called "Adenosine TriPhosphate" or simply (ATP). And that's how oxygen is converted into energy in the brain.
You can think of the ATP's role as the role of the lithium battery in your cell phone!
This how the Adenosine molecule looks like when it has no energy (like an empty battery!) it's just "A"!
And this is how it looks when it's fully charged (notice the extra tail of chemical bonds!) its "A+3P"!
When body needs energy, it breaks down these extra chemical bonds (3P) which have energy stored in them, returning the "ATP" to its uncharged form "A". And to recharge these molecules all what we have to do is to eat and breathe :)
We need a science teacher to explain for both of us if you don't know it,but I'll try to look it up.
