why does the human body need O2 in oder to get rid of Carbon? Why cant it just release the carbon as a gas or something?
The body doesn't just take an O2 and stick a carbon onto it. The body has a very complicated set of chemical reactions, called the [Krebs cycle](_URL_0_), that it uses for energy. The Krebs cycle is how your cells turn your food into usable energy to do stuff and stay alive.
The Short Answer
The body doesn't just take an O2 and stick a carbon onto it. The body has a very complicated set of chemical reactions, called the [Krebs cycle](_URL_0_), that it uses for energy. The Krebs cycle is how your cells turn your food into usable energy to do stuff and stay alive. It takes your food nutrients, like carbs and protein, and breaks them down to recharge a chemical called adenosine triphosphate (ATP). ATP is a little messenger molecule that carries energy from place to place inside your cells. When it runs out of energy it has to be recharged by another run through the Krebs cycle. One of the steps in the Krebs cycle requires oxygen. This is why you need to breathe in oxygen to live. And in addition to ATP, there are two byproducts of the cycle: carbon dioxide, and water. You get rid of the CO2 by exhaling it.
