WebHemoglobin is found in the red blood cells of the body. Each red blood cell (RBC) contains approximately 280 million hemoglobin molecules (Sears, 1999). The main function of hemoglobin is to transport oxygen from the lungs to the tissues and then transport CO2 back from the tissues to the lungs. Web21 sep. 2024 · Hemoglobin is a protein found in red blood cells. It contains iron, which allows it to transport oxygen. Each hemoglobin molecule can bind up to four oxygen molecules. 3 This way, it can transport the oxygen from the lungs to the tissues that need it. Oxygen is important for normal cellular metabolism.
Web17 jan. 2024 · Red blood cells contain hemoglobin,which contains four iron-binding heme groups. Oxygen binds the heme groups of hemoglobin. Each hemoglobin molecule can bind four oxygen molecules. The binding affinity of hemoglobin for oxygen is cooperative. It is increased by the oxygen saturation of the molecule. WebHemoglobin is an oxygen-carrying protein molecule present in Red blood cells of human beings. Each RBC has approximately 270 million Haemoglobin molecules. Thus in an average human body, the number of hemoglobin molecules are 6000 million million million. So, the correct answer is '6000 million million million'. Was this answer helpful? 0 0
