How does an increase in blood P_CO2 and a subsequent decrease in blood pH (the Bohr effect) affect the oxygen-hemoglobin dissociation curve?
- The curve shifts to the left, increasing oxygen affinity to help load oxygen in the lungs.
- The curve becomes linear, indicating that hemoglobin has lost its cooperative binding property.
- The curve shifts upward, indicating that hemoglobin can carry more total oxygen.
- The curve shifts to the right, decreasing oxygen affinity to promote oxygen unloading in tissues.
