2) Write the equili
ium constant expression for the reaction shown in question 1.
(2 marks)
3) Calculate the equili
ium constant using the following concentrations
[Hb] = 2.27 x 10-8 M, [O2] = 9.5 x 10-2 M and [HbO2] = 6.93 x 10-1 M.

PART B - 600 words +/- 10% (30 marks)
The combination of oxygen (O2) with hemoglobin (Hb), is a complex reaction, but for our
purposes here, it can be represented by a simplified equation:
Hb (aq) + O2 (g) HbO2 (aq)
where HbO2 is oxyhemoglobin, the hemoglobin-oxygen complex that transports oxygen
to tissues. Consider the above reaction and address the following:
1) Explain the connection between O2, Hb and red blood cells XXXXXXXXXXmarks)
2) Hb transport protein requires a particular metal ion to effectively transport oxygen
around the body. Research which ion this is and state if it is a cation or an anion.
Discuss the significance of this ion in relation to oxygen transport. (3 marks)
3) Explain why O2 requires the transport protein Hb and state the percentage of oxygen
transported around the body by Hb XXXXXXXXXXmarks)
4) Explain where in the body the forward reaction and reverse reactions are most likely
to occur, making reference to partial pressures of O2 in your explanation. (6 marks)
5) Ca
on dioxide is a metabolic waste product. Explain the three ways in which ca
on
dioxide is transported around the body XXXXXXXXXXmarks)
6) Write a chemical equation for the major way ca
on dioxide is transported around
the body and explain why this reaction is important in the human body. (4 marks)
7) Which way will the equili
ium shift for the reaction in Question 6 if ca
on dioxide
levels were higher than normal? What would be the consequences of this
happening (from a chemical perspective) and how would this affect the health of an
individual? XXXXXXXXXXmarks)
