We inhale O2 and exhale CO2, so does that mean we just add carbon and exhale the same oxygen we just inhaled? Why cant we just exhale carbon?
In: Biology
The oxidation of hydrocarbons provides energy for other chemical reactions essential to live. If you just exhaled sugar, for example, you wouldn’t have been able to utilize it for energy after consuming it.
In other words, Oxygen is used to burn carbon, and CO2 is the result of burning carbon compounds against oxygen for energy.
