Q. Regarding the O2 dissociation curve: (Solved)
1. O2 affinity of Hb is reduced when the curve is shifted to the left
2. decreased 2,3-DPG shifts the curve to the right
3. the Bohr effect is attributed to the action of PCO2 on H+ concentration
4. temperature has no effect on the curve
5. 2,3-DPG levels are reduced at altitude
- c. the Bohr effect is attributed to the action of PCO2 on H+ concentration
