At normal temperature and pressure only 4 ml of oxygen is dissolved in one liter of water or plasma. So molecule of hemoglobin is designed by nature in such a way that, it contains 4 atoms of iron in it ( and so it carries 4 molecules of oxygen ) and have affinity for oxygen, large enough to hold it, when there is high concentration of oxygen, as in lung and small enough to let the oxygen go, where the concentration of oxygen falls down in interstitial compartment . That's the beauty of hemoglobin molecule. So blood can carry 70 times more oxygen than what water or plasma can do. It means about 280 ml / liter.

A molecule of hemoglobin can hold how many molecules of oxygen in the blood transport?
Four heme groups, so I think four molecules of oxygen can be transported by one molecule of haemoglobin.
The association of four subunit peptides in a fully functional molecule of hemoglobin is a good example of?
The quaternary structure of proteins.
Is the B-subunit of the hemoglobin A molecule a complete DNA molecule?
B-subunit of the hemoglobin A molecule is not a complete DNA molecule. It contains 4 subunits
Is the B subunit of the hemoglobin A molecule a complete DNA molecule?
B-subunit of the hemoglobin A molecule is not a complete DNA molecule. It contains 4 subunits
The molecule responsible for carrying oxygen through the human body is?
hemogoblin
A fully functional molecule of hemoglobin is what kind of protein structure?
The structure of the hemoglobin in a molecule is the quaternary structure.
Each hemoglobin molecule is able to transport molecules of oxygen.?
False. The mammalian hemoglobin molecule can bind (carry) up to four oxygen molecules.
What is the name of the thing in our blood that transport oxygen?
Red blood cells are packed full of a protein called hemoglobin. Hemoglobin has a molecule of iron in each protein molecule. This hemoglobin is what carries oxygen. The oxygen binds with the iron.
Which part o the hemoglobin molecule does carbon dioxide attach?
Hemoglobin refers to a red protein responsible for transporting oxygen in the blood of vertebrates. The part of the hemoglobin molecule that carbon attaches to is the heme molecule.
What is the length of hemoglobin molecule?
6.8*10-6mm is the length of a hemoglobin molecule
What happens when hemoglobin is degraded?
The part of the blood that is responsible for carrying oxygen is hemoglobin. The hemoglobin binds to oxygen in the alveoli of the lungs. Then the hemoglobin releases the oxygen at the cells. The part of the hemoglobin molecule that is directly responsible for carrying the oxygen is the iron ion in the center of the molecule's structure. The iron ion changes from a Fe +2 ion to a Fe +3 when carrying the oxygen. Then the hemoglobin reaches the cell, the iron ion decomposes back to the more stable Fe +2 state, replacing the oxygen with a water molecule.

The quaternary structure of proteins.

Is the B subunit of the hemoglobin A molecule a complete DNA molecule?
B-subunit of the hemoglobin A molecule is not a complete DNA molecule. It contains 4 subunits
What substance is transported by hemoglobin?
The hemoglobin molecule is what the oxygen molecule will attach to in the red blood cell.
The molecule responsible for carrying oxygen through the human body is?
hemogoblin
