B3.1 Gas exchange HL Flashcards
1
Q
What is the Bohr shift?
A
Shift in oxygen dissociation curve due to CO2.
2
Q
Oxyhaemoglobin
A
Haemoglobin bound to oxygen
3
Q
Cooperative binding in haemoglobin?
A
One oxygen molecule increases haemoglobin’s affinity
4
Q
Allosteric Binding
A
Binding of CO2 to haemoglobin at non-active site
5
Q
Difference between foetal and adult haemoglobin?
A
Foetal has higher oxygen affinity
6
Q
Cooperative binding in haemoglobin?
A
Increases affinity for more oxygen
7
Q
Cause of the Bohr shift in haemoglobin?
A
High CO2 reduces oxygen affinity
8
Q
Oxyhaemoglobin
A
Haemoglobin bound to oxygen
9
Q
Adult vs foetal haemoglobin?
A
Foetal has higher oxygen affinity
10
Q
Allosteric Binding
A
Binding at a site other than the active site
