Which section of chapter 6 are you referring to (assuming you are talking about a chapter 6 question)? There are three/four sections ( eg. 6A, 6D)!

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 H3O1(aq) 1 HbO22 (aq) ∆ HHb(aq) 1 H2O(l) 1 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 HbO22? (b) When the hemoglobin returns to the lungs, where oxygen concentration is high, how does the concentration of HbO22 change?
