Step-by-step explanation:
The process in which Haemoglobin works depends by the environmental conditions of blood, especially with the partial pressures of O₂ and CO₂ related with the concentration of these compounds. When blood enters in the lungs, the haemoglobin get oxygenated because there is a high concentration of O₂ (meaning that the partial pressure of oxygen is high), liberating CO₂ that will be exhaled. The haemoglobin saturated with oxygen is known as oxyhaemoglobin
When blood flows in the body, found in the tissues higher concentrations of CO₂ which is more efficiently united with the haemoglobin, liberating the oxygen in the tissues for cell respiration, the haemoglobin them has form a reaction with the CO₂ which will travel back to the lungs and the cycle will begin again.
The three ways in which CO₂ travel are: Diluted in the plasma, as bicarbonate and combined with proteins (Haemoglobin) as a carbamine compound.
The CO₂ diluted in plasma, is due to the great capacity of dilution of the CO₂ which could be almost 20 times higher than O₂ capacity of dilution.
Bicarbonate is formed in the red blood cell when CO₂ and the enzyme name carbonic anhydrase reacts with water, forming a carbonic acid, when the concentration of these ions is elevated the carbonic acid becomes bicarbonate liberating a H₊ wich is united in the haemoglobin.
Carbamine compound form in the proteins families of the globines, being the most important the reaction in the haemoglobin.
