CO2 is a byproduct of cellular metabolism. Cells take in oxygen and glucose and release water, carbon dioxide, and energy. CO2 plays an important role in acid–base buffering. Depending on blood pH at any given time, CO2 converts either to carbonic acid (H2CO3, an acid) or to bicarbonate (HCO3-, a … See more Gases diffuse from areas of higher concentrations to areas of lower concentration.
