6.8*10-6mm is the length of a hemoglobin molecule
B-subunit of the hemoglobin A molecule is not a complete DNA molecule. It contains 4 subunits
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
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.
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 diameter of Hb molecule is app. 5.5 nm, and that is larger than a glucose molecule.
No, the B-subunit of hemoglobin A is a protein subunit, not a DNA molecule. Hemoglobin is composed of four protein subunits (two alpha and two beta) that come together to form the hemoglobin molecule, which carries oxygen in red blood cells. The instructions for making these protein subunits are found in the DNA of our cells.
after one oxygen molecule binds to hemoglobin, it is easier for the other molecules to bind to the hemoglobin. this is known as cooperative binding.
Iron. This element is found at the center of each hemoglobin molecule.
iron
loss of only one amino acid from the normal hemoglobin molecule
