Haemoglobin

what is the primary structure of a protein
the sequence of the amino acids
1 of 10
what is the secondary structure of protein
in which of these polypeptide chains is coiled in a helix
2 of 10
what is the tertiary structure of a protein
Protein folded even more to have ionic bonding,disulphide bridges and covalent bonding
3 of 10
what is the quaternary structure of a protein
All the four polypeptides are linked each polypeptide is associated with a haem group
4 of 10
what is the role of haemoglobin
to readily associate with oxygen at the surface where oxygen takes place, readily dissociate from oxygen at respiring tissues
5 of 10
If the oxygen dissociate curve is further to the left what does it show
the haemoglobin has a greater affinity for oxygen
6 of 10
if the curve is further to the right what does it show about the oxygen dissociate curve
the lower the affinity of haemoglobin for oxygen
7 of 10
what does a greater concentration of carbon dioxide do to the haemoglobin dissociation curve
haemoglobin releases its oxygen more readily
8 of 10
in rapidly respiring tissues the concentration of carbon dioxide is high what does this do to the affinity of haemoglobin
The affinity of haemoglobin for oxygen is reduced and it shifts the dissociation curve more to the right
9 of 10
when co2 is low what does this do to to the affinity of haemoglobin for oxygen
it increases it.
