The production of carbon dioxide during respiration in aerobic tissues lowers the pH in erythrocytes, which in turn ________ the affinity of oxygen binding to hemoglobin.
A. Decreases
B. Increases
C. Equalizes
Homework Answers
Ans) The correct option is A because the binding affinity of oxygen to hemoglobin is inversely proportional to the binding of H+ ions or (low pH in this case). We already know that more acidic the pH is, more the number of H+ ions and thus,this will result in decrease in the affinity of oxygen for hemoglobin.
