Answer 1

Answer:

the erythrocytes occur and haemoglobin ends up binding to NO and O2.

Diffusion of oxygen into the body cells occur when haemoglobin releases its content in the capillaries. The capillary walls are relaxed by NO to allow expansion thus facilitating the transport of oxygen to the cells.

Haemoglobin is composed of four subunits each containing a cofactor known as a haem group that includes an iron atom center. The main component that binds with oxygen is the iron. Hence each molecule of haemoglobin is capable of carrying four oxygen molecules.

In order to transport oxygen efficiently, corporation between the four subunits in a haemoglobin molecule becomes mandatory. In truth, all four subunits bind with oxygen collectively. When oxygen gets bound to one site among the four subunits, it also increases the chances of other remaining sites being bound to oxygen. Haemoglobin’s role in carrying oxygen through the blood from the lungs to the tissues is considered crucial for survival.
