Main function of hemoglobin
WebThe main function of Hb is to take up O 2 from the lungs and deliver it to tissues. It can undergo conformational changes (e.g., depending on its state of oxygenation), which influence how it binds and releases O 2 and CO 2. Deficient or defective Hb can ultimately affect the transport of O 2 (see “ Hemoglobin variants ” below for details). Web31 mrt. 2024 · Hemoglobin is a protein in your red blood cells that carries oxygen to your body’s organs and tissues and transports carbon dioxide from your organs and tissues back to your lungs. If a hemoglobin test reveals that your hemoglobin level is lower than normal, it means you have a low red blood cell count (anemia).
