The majority of carbon dioxide is carried
through the blood by conversion from carbon
dioxide, CO2 into bicarbonate ions,
HCO3-,which allows it to dissolve as a
salt in the blood and be carried along. This
reaction is catalyzed by the protein carbonic an
hydrase.As carbon dioxide is a waste product of
our cellular respiration, it is shuttled to the
lungs, where it can come out of solution back
intogas, and exit our body when we breathe out.
