ACO2 diffuses out of cells into systemic capillaries
BOnly 7% of the CO2 remains dissolved in plasma
CNearly a fourth of the CO2 binds to hemoglobin, forming carbaminohemoglobin
D70% of the CO2 load is converted to bicarbonate and H+. Hemoglobin buffers H+.
EHCO3- enters the plasma in exchange for Cl- (the chloride shift)
FAt the lungs, dissolved CO2 diffuses out of the plasma
GBy the law of mass action, CO2 unbinds from hemoglobin and diffuses out of the RBC
HThe carbonic acid reaction reverses, pulling HCO3- back into the RBC and converting it back to CO2
