AQA AS Biology - Mass Transport 3.3.4 Questions & Answers 2024 
What is the structure of haemoglobin? - ANS-A quaternary structure with 4 polypeptide chains (2 alpha, 
2 beta) 
Each chain associated to a haem group containing an Fe2+ ion 
Each Fe2+ can carry one oxygen 
- hence Hb can carry a maximum of 4 oxygen 
What is the role of haemoglobin? - ANS-Transport oxygen around the body 
How does haemoglobin transport oxygen? - ANS-When ppO2 is high - at lungs - Hb has a high affinity for 
oxyge...
