WebEach iron ion in the heme can bind to one oxygen molecule therefore each hemoglobin molecule can transport four oxygen molecules. An individual erythrocyte may contain about 300 million hemoglobin molecules and therefore can bind to and transport up to 1.2 billion oxygen molecules (see (Figure)b).

Once oxygen has entered the blood from the lungs, it is taken up by haemoglobin (Hb) in the red blood cells. Each subunit has a heme group in the centre that contains iron and binds one oxygen molecule. This means each haemoglobin molecule can bind four oxygen molecules, forming …
WebMyoglobin is a protein that facilitates the transfer of oxygen in muscles. It was the first protein to be fully elucidated with regard to the three-dimensional arrangement of its atoms. Hemoglobin, the oxygen-carrying pigment of blood, is composed of four heme groups attached to four polypeptide chains. Like hemoglobin, myoglobin is a cytoplasmic protein that binds oxygen on a heme group. It harbors only one globulin group, whereas hemoglobin has four. Although its heme group is identical to those in Hb, Mb has a higher affinity for oxygen than does hemoglobin. This difference is related to its different role: whereas hemoglobin transports oxygen, myoglobin's function is to store oxygen.
WebQuestion. a) How much more O2 can be transported by the blood when erythrocytes. leave the lungs? Consider that a normal adult has a concentration of 15 g hemoglobin/100 mL of blood. and that the hemoglobin is 98% saturated with O2 at the usual pO2 of 100 torr in the lung at sea level. b) On the basis of the graph, explain how myoglobin ...
