Answer:
Hemoglobin is a protein found in red blood cells that is comprised of two alpha and two beta subunits that surround an iron-containing heme group. Oxygen readily binds this heme group. The ability of oxygen to bind increases as more oxygen molecules are bound to heme.

Answer:
the binding of haemoglobin depends upon it's partial pressure in the region.
[partial pressure is the individual pressure exerted by the gas, in this case- oxygen]
In the lungs, the partial pressure of oxygen in the blood vessels carrying deoxygenated blood is lower, so oxygen diffuses through the alveolar membrane into the blood vessel making it oxygenated blood.
[alveolar membrane- covering membrane of the alveoli which is the smallest unit of the lung]
When the oxygenated blood reaches the cells, the partial pressure in the cells is lower than that in the blood vessels carrying oxygenated blood, so oxygen diffuses into the cells, supplying oxygen to the cells.
Here, wherever I have mentioned blood, oxygen binds to haemoglobin in the blood and binding of oxygen depends upon the partial pressure of oxygen and carbondioxide
