CAPE Biology Unit 2 · 2004 · Paper 2 · Question 6(b)(ii)
On earth, at sea level, an oxygen partial pressure of 5 kPa results in a 50% saturation of haemoglobin by oxygen, and a partial pressure of 10 kPa results in a 95% saturation of haemoglobin. What would be the effect, in the space capsule, of the high CO2 concentration on the percentage saturation at 5 kPa and 10 kPa, AND how would it alter the oxygen dissociation graph curve?
