Explanation:
(c) Haemoglobin has 4 subunits, each of which binds to 1 molecule of ${{\text{O}}_{2}}$ for a total of 4 molecules of ${{\text{O}}_{2}}$ bound to
1 haemoglobin molecule.

What percentage of oxygen is carried by haemoglobin?
1 90
2 97
3 23
4 73
Explanation:
(b) About $97\text{ }\!\!%\!\!\text{ }$ of ${{\text{O}}_{2}}$ is transported by RBC. ${{\text{O}}_{2}}$ binds with haemoglobin (red coloured iron containing pigment present in the RBCs) to form oxyhaemoglobin. This process is known as oxygenation.
