As the pH of the blood decreases, H+ ions increase, which combines with the protein part of hemoglobin, to decrease its ability to bind with:
Correct answer: A. O2
- A. O2
- B. CO2
- C. CO
- D. H2
Explanation
The Bohr effect describes hemoglobin's lower affinity for oxygen secondary to increases in the partial pressure of carbon dioxide and/or decreased blood pH. This lower affinity, in turn, enhances the unloading of oxygen into tissues to meet the oxygen demand of the tissue.
