The purpose of hemoglobin biology essay
Blood is an extremely important fluid for the body. It is thicker than water and feels a bit sticky. The temperature of the blood in the body is C 100, which is about one degree higher than body temperature; Red blood cells, also called erythrocytes, deliver oxygen to the tissues in your body. Oxygen becomes energy and your tissues release carbon dioxide. Your red blood cells also transport carbon dioxide to your lungs so you can exhale. Cleveland Clinic is a nonprofit academic medical center. Advertising on our site helps support our mission. The sigmoid shape of the oxygen dissociation curve shows why hemoglobin is so ideally suited for its role in oxygen transport. The shape of the curve is explained by the remarkable property of hemoglobin: cooperative binding. Hemoglobin has four tertiary domains, each with its own binding site. So it can carry four types of oxygen. · Oxygen-hemoglobin dissociation Hemoglobin-oxygen affinity. As shown in the oxygen-hemoglobin dissociation curve above, the amount of oxygen bound to hemoglobin and oxygen saturation are affected by the partial pressure of oxygen in the blood. However, this relationship and the shape of the curve are,
