... myself all wound up here. There is a difference in the way both gases travel in the blood. The vast majority of O2 binds to hemoglobin (w/ a weak, reversible bond) and approx 70% of CO2 is bound to HCO3-. But I do know that approx. 23% of CO2 is bound to hemoglobin. Am I in the right direction ...

... 02 levels fall in arterial blood?? Does it have to do with differences in partial pressure gradients for the two gases? Or what about the weak and reversible bond between O2 and hemoglobin? Or the Bohr effect, where in the presence of higher concentrations of CO2 or H+ , the affinity of O2 for ...

I didn't say that as clearly as I should have. "Reversible" means that the same enzyme catalyzes both the forward and reverse reactions. "Steady-state" means that the two reactions "cancel out."
