Why do we become short of breath?

False, while you need oxygen to release the energy in muscles (to move), once there is enough oxygen, adding more does not create more energy. The energy comes form the food you eat, not the oxygen used to burn it.
What happens if levels of carbon dioxide or oxygen in your body change?
if the oxygen levels are too low, your muscles won't get the oxygen they need from the blood cells. if the carbon dioxide levels are too high, well, carbon dioxide is a waste product, the same thing will happen. this is why when you hold your breathe you pass out. if the muscles don't get the oxygen they need they can't move.
