How do body cells transform oxygen into carbon dioxide?

I want to know about how the body cells change the gas for the cellular respiration. I already know about the path the gases go through prior to and after they reach the body cells.

1. The detailed path of the chemical reaction of cell respiration is pretty complicated. The net result is pretty simple and intuitive in that it is like other energy producing reactions we are used to. It is basically burning. The cells take the carbon-containing energetic molecules that are reduced from the food we eat (plants and animals are "organic", carbon containing) and "burns" this carbon with oxygen from breathing. The result from burning carbon is carbon dioxide. This is about the same as burning charcoal in air. Carbon charcoal reacts with oxygen and the result is CO2.
