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 length of hemoglobin molecule?
6.8*10-6mm is the length of a hemoglobin molecule
What element makes the blood this colour?
Iron Hemoglobin which contains iron, so that it con bind oxygen. Although Iron is an element. Hemoglobin is a molecule.
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
What type of macro-molecule is hemoglobin?
A protein, which is made up of amino acids.
A fully functional molecule of hemoglobin is what kind of protein structure?
The structure of the hemoglobin in a molecule is the quaternary structure.
What substance is transported by hemoglobin?
The hemoglobin molecule is what the oxygen molecule will attach to in the red blood cell.
Hemoglobin is what type of molecule?
A protein Molecule
What pigment is released when a hemoglobin molecule is broken apart?
When a hemoglobin molecule is broken apart, the iron pigment is released. This is what is called the -"heme" part of the molecule.
How many molecules of oxygen bind to one molecule of hemoglobin?
Haemoglobin combines with four molecules of oxygen.
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.
