250 million X 4 = < 1 billion
4- is how many o2 molecules a single HBn carries assuming they are full saturated(which they almost never are)
Actually, one hemoglobin molecule can carry 4 molecules of oxygen. There are ~1 billion molecules of oxygen in each RED BLOOD CELL.
One hemoglobin molecule in a red blood cell can bind up to four oxygen molecules. Therefore, one blood cell could potentially carry up to four oxygen molecules at a time.
Hemoglobin is a protein, i.e. a molecule, not a cell. About 97% of the "dry content" of red blood cells is hemoglobin. The exact number of hemoglobin protein molecules is not particularly well defined since red blood cells vary in weight but the range could probably be estimated from that 97% statistic.
Each Red Blood Cell can carry up to four oxygen molecules, which bind to hemoglobin proteins in the cell. This binding of oxygen to hemoglobin is crucial for the transport of oxygen from the lungs to tissues throughout the body.
each Red blood cell is capable of transporting oxygen, and carbon dioxide.
Sickle cell hemoglobin can carry one oxygen molecule.
Red blood cells contain approximately 270 million hemoglobin molecules, each of which has four heme groups. Therefore, the total number of heme groups in a single red blood cell is around 1.08 billion. Hemoglobin is responsible for transporting oxygen throughout the body, with the heme groups playing a crucial role in binding oxygen molecules.
Four heme groups, so I think four molecules of oxygen can be transported by one molecule of haemoglobin.
Haemoglobin combines with four molecules of oxygen.
In saturated hemoglobin, each hemoglobin molecule can bind to four molecules of oxygen. Therefore, in saturated hemoglobin, there would be a total of four molecules of oxygen bound to each hemoglobin molecule.
The red blood cell is just about the easiest cell to study , it has haemoglobin (lots of it) it has a nucleus when it forms from bone marrow , but when it matures it loses the nucleus and is replaced by ..... can u guess ? MORE HAEMOGLOBIN , as well as some other chemicals / components , it has a cell membrane otherwise known as : lipid bilayer ( a thin membrane made of molecules ) as well as a few other minor to average components.
When an oxygen molecule moves from inside an alveolus to the hemoglobin of a red blood cell, it crosses two plasma membranes. The first is the alveolar epithelium's plasma membrane, separating the alveolus from the capillary, and the second is the red blood cell's plasma membrane, where the oxygen binds to hemoglobin for transport. Plasma membranes are the outer boundary of cells that regulate the passage of substances in and out of the cell.
An erythrocyte, or red blood cell, is a small, biconcave disc-shaped cell without a nucleus. It is filled with hemoglobin, which enables it to transport oxygen and carbon dioxide throughout the body. Erythrocytes are flexible and able to deform to squeeze through small blood vessels.
