Question

Functions of haemoglobin?

Answer 1

The major role of hemoglobin is to carry oxygen from the lungs to the tissues and return carbon dioxide (CO2) from the tissue to the lungs. It is the oxygen carrying component of RBCs. Oxygen binds to hemoglobin with high affinity in an oxygen-rich environment and leaves hemoglobin in an environment where there is not enough oxygen.

• It is the protein in red blood cells (RBCs).

• Hemoglobin functions by binding and transporting oxygen from the capillaries in the lungs to all of the tissues in the body.

• It also plays a role in the transport of carbon dioxide from the tissues of the body back to the lungs.

• Nitric oxide and carbon monoxide are also able to bind with hemoglobin, with carbon monoxide binding much more readily than oxygen.
