Where is haemoglobin found?
Red Blood Cells
1 of 14
What is a quaternary structure?
More than one polypeptide chain
2 of 14
What do oxygen and haemoglobin combine to form?
Oxyhaemoglobin
3 of 14
What is the haem group?
An iron ion
4 of 14
Define Oxygen Affinity:
Haemoglobin's tendency to combine with oxygen
5 of 14
What is partial pressure of Oxygen? (pO2)
The concentration of oxygen present.
6 of 14
Where is there a high pO2?
The alveoli in the lungs
7 of 14
Where does haemoglobin have a lower oxygen affinity?
At respiring tissues (more CO2)
8 of 14
What is the Bohr effect?
This is where higher PCO2 causes a lower oxgyen affinity, caused by respiring cells. This allows more oxygen to be released into the cells during activity.
9 of 14
Does Foetal haemoglobin have a higher or lower O2 affinity than Maternal haemoglobin?
Higher - this is because the only way to absorb oxygen is through the mother, so it must be strong at absorbing
10 of 14
Put the types of haemoglobin in order of affinity (lowest first):
Bohr -> Normal -> Foetal -> Myoglobin
11 of 14
Where is Myglobin found?
In muscles
12 of 14
True or false: Higher affinity animals have an oxygen dissociation graph that is shifted to the left
True
13 of 14
What would the Oxygen-Dissociation curve of a mouse look like?
Shifted to the right, high metabolism, Bohr Effect
