Cellular Respiration

We breath in the air which has oxygen nitrogen and lots of other things, but what we need in the oxygen. We also need glucose which is just energy to have it work which we get by other means than plants do. And it goes to our lungs and it ends up creating ATP which is energy for all our cells to make up tissue, water which you can tell if you breath on you hand it gets slightly sticky from condensation and we also breath out carbon dioxide into the air which plants use for photosynthesis.
