When you breath in oxygen, that oxygen undergoes a process called cellular respiration in order to provide energy for your cells. I won't go into detail with the entire process, but basically a sugar (C6H12O6) combined with oxygen (6O2) to create carbon dioxide (6CO2) and water (6H2O). Since the carbon dioxide is a waste product, we release it when we exhale. If you're wondering what happens to it, plants use it to undergo a process called photosynthesis, which is basically the oppisite of cellular respiration; needing carbon dioxide and water while producing a sugar and oxygen, and they then give the oxygen off as a wast product. That's all hope this helped!

The carbon dioxide you exhale comes from the food you eat. When you digest food, your body breaks it down into carbon dioxide and other byproducts that are released when you breathe out.

What gas come out when you exhale?

When you exhale, you release carbon dioxide, which is a waste product of cellular respiration in your body. Inhaling oxygen is used by your cells to produce energy, and carbon dioxide is a byproduct that is then expelled when you breathe out.

When you exhale do you breathe out carbon monoxide or carbon dioxide?

When you exhale, you breathe out carbon dioxide, not carbon monoxide. Carbon dioxide is a natural byproduct of cellular respiration in the body and is transported to the lungs where it is exhaled. Carbon monoxide is a toxic gas produced by incomplete combustion of carbon-containing fuels.
