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.
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.
One RBC contains about 250 million Hemoglobin molecules
Each molecule of hemoglobin can transport up to four molecules of oxygen. Hemoglobin has four heme groups, each of which can bind to one molecule of oxygen.
