Carbon dioxide



A chemical compound composed of two oxygen atoms linked to a single carbon atom by covalent bond, and essential to many biochemical and biological processes.


In animals, carbon dioxide is a chemical compound that accumulates in the tissues and removed from the body when an animal exhales. It is therefore a metabolic byproduct of carbohydrate metabolism.

In plants, carbon dioxide is an important reactant to produce sugars by photosynthesis.

Chemical formula: CO2

Also called: carbonic acid gas
