Does myoglobin have the same high affinity for CO as hemoglobin?

Why does release of BPG in the blood system help counter the effects of high altitude induced hypoxia? O BPG binds each hemoglobin tetramer and leads to formation of a confirmation that binds 02 more strongly allowing uptake of 02 in the lungs BPG binds myoglobin and leads to formation of a confirmation that binds 02 more strongly allowing uptake of O2 in the lungs BPG binds myoglobin and leads to formation of a confirmation that binds 02 more weakly allowing release of 02 in oxygen starved tissues O BPG binds each hemoglobin tetramer and leads to formation of a confirmation that binds 02 more weakly allowing release of 02 in oxygen starved tissues

1. Is this statement correct or incorrect? Explain.  During strenuous exercise, the oxygen-hemoglobin dissociation curve shifts to the right. This rightward shift reflects an increase in the affinity of hemoglobin for oxygen and favors loading of O2 onto hemoglobin in the lungs. 2. Is this statement correct or incorrect? Explain.  Compared to hemoglobin, myoglobin has a lower binding affinity for O2 and a higher O2 binding capacity, two characteristics that allow myoglobin to efficiently provide skeletal muscle cells with a readily-accessible reservoir of O2.

Approximately how much CO2 is carried by hemoglobin in the venous blood?
