6.19

Hemoglobin (Hb) molecules in blood carry O2 molecules from the lungs, where the concentration of oxygen is high, to the tissues where it is low (see the Interlude following Focus 5). In the tissues the equilibrium H3O+(aq) + HbO2- (aq) : HHb(aq) + H2O(l) + O2(aq) releases oxygen. When muscles work hard, they produce lactic acid as a byproduct. (a) What effect will the lactic acid have on the concentration of HbO2-? (b) When the hemoglobin returns to the lungs, where oxygen concentration is high, how does the concentration of HbO2- change?

This question appears on the syllabus for the acid and base equilibrium section. Will we have to know this information for Test 1?

I think it would be good to know this information just in case it shows up on the test.
