WebOct 5, 2024 · Hemoglobin is a protein that binds with oxygen in the human bloodstream and delivers it to cells throughout the body. Inside each red blood cell are 200-300 million molecules of hemoglobin (Hb) molecules. Hemoglobin is a large molecule composed of two alpha subunits and two beta subunits. 1. WebHemoglobin is the oxygen-carrying pigment in the red blood cells that transports oxygen from the air in the lungs to the tissue fluid around the cells. Recall that one molecule of hemoglobin can bind four molecules of oxygen. One oxygen molecule is attached to each of the four heme groups present in hemoglobin.

WebHaem binds oxygen so that each haemoglobin molecule can bind up to four oxygen molecules. When all the haem units in the blood are bound to oxygen, haemoglobin is considered to be saturated. Haemoglobin is partially saturated when only some haem units are bound to oxygen.
