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.
Hemoglobin consists of four subunits, each of which has a binding site for oxygen. Therefore, four oxygen molecules can bind to one hemoglobin.
Basically when oxygen binds into an red blood cell, the red blood cell absorbs as much oxygen as possible in the hemoglobin molecule. In the process the hemoglobin becomes oxyhemoglobin.

How many oxygen molecules could one blood cell carry?
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.
How many hemoglobin cells are in each red blood cell?
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.
How many oxygen molecules can each Red Blood Cell carry?
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.
How many red blood cell is capable of transporting oxygen molecules?
One red blood cell is capable of transporting millions of oxygen molecules through the hemoglobin protein contained within the cell.
How many oxygen molecules sickle cell hemoglobin carry?
Sickle cell hemoglobin can carry one oxygen molecule.
A molecule of hemoglobin can hold how many molecules of oxygen in the blood transport?
One molecule of hemoglobin can hold up to four molecules of oxygen for transport in the blood.
How many molecules of oxygen bind to one molecule of hemoglobin?
Haemoglobin combines with four molecules of oxygen.
How many molecules of oxygen are present in saturated hemoglobin?
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.
Parts of red blood cells?
Red blood cells consist mainly of hemoglobin, a protein that carries oxygen. They also contain enzymes, ions, and small molecules that help maintain cell structure and function. The outer membrane of red blood cells is composed of lipids and proteins that regulate the cell's shape and flexibility.
How many times does an oxygen molecule cross a plasma membrane when moving from inside an alveolus to the hemoglobin of a red blood cell and what are the plasma membranes?
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.
What is the structure of an erythrocyte?
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.
How many molecules of oxygen can be transported by one molecule of hemoglobin?
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.
