Hemoglobin Production at High Altitude

As we learned at the end of Chapter 11, rapid ascent to a high altitnde can cause altitude sickness. The symptoms of altitude sickness, including dizziness, headache, and nausea, are caused by hypoxia, an insufficient oxygen supply to body tissues. In severe cases, without prompt treatment, a victim may slip into a coma and die. And yet a person staying at a high altitude for weeks or months can recover gradually from altitude sickness, adjust to the low oxygen content in the atmosphere, and live and function normally. 

The combination of oxygen with the hemoglobin (Hb) molecule, which carries oxygen through the blood, is a complex reaction, but for our purposes it can be represented by the following simplified equation  

1 Which of the following equilibria will shift to the right when H2 is added (Select all that apply.) 

3 Which of the following equilibria will shift to the left when
