what is significance of respiratory pigment in respiration

Open in App
Solution

Dear student,

The respiratory pigment present in humans is haemoglobin. Its main function is to transport oxygen to various parts of the body. When the blood passes through the lungs, haemoglobin takes up oxygen from the lungs and bind to it. One molecule of haemoglobin binds to four molecules of oxygen. Oxygen-haemoglobin complex is then transported to various parts of the body.and oxygen is released into the tissues.

Apart from oxygen transportation, haemoglobin has some role in transportation of carbon dioxide from body parts to lungs. About 10% of carbon dioxide transportation occurs through haemoglobin.
