4 polypeptide chains, each containing a heme group with an iron atom attached
Type your answer here... white blood cells, red blood cells
Hemoglobin is a protein with repeating segments called heme, each of which contains an iron atom, which is the active site where oxygen can be carried.
Red Blood Cells
It is composed of a protein chain.
DNA
False. The mammalian hemoglobin molecule can bind (carry) up to four oxygen molecules.
6.8*10-6mm is the length of a hemoglobin molecule
Iron Hemoglobin which contains iron, so that it con bind oxygen. Although Iron is an element. Hemoglobin is a molecule.
B-subunit of the hemoglobin A molecule is not a complete DNA molecule. It contains 4 subunits
B-subunit of the hemoglobin A molecule is not a complete DNA molecule. It contains 4 subunits
A protein, which is made up of amino acids.
The structure of the hemoglobin in a molecule is the quaternary structure.
The hemoglobin molecule is what the oxygen molecule will attach to in the red blood cell.
A protein Molecule
When a hemoglobin molecule is broken apart, the iron pigment is released. This is what is called the -"heme" part of the molecule.
Haemoglobin combines with four molecules of oxygen.
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.
