Is the mineral that combines with a protein to from hemoglobin?
There are four atoms of iron in a molecule of hemoglobin. Each iron atom is attached to a porphyrin, forming a heme group. Each heme group is attached to a polypeptide chain. There are two alpha and two beta polypeptides. So a hemoglobin molecule has four heme groups, and four polypeptides.
Each heme contains an atom of iron and can transport one molecule of oxygen?
true
Each heme region of a hemoglobin molecule contains an inorganic element called?
iron
What is heme biosynthesis?
Much of the heme biosynthesis pathway is dedicated to constructing the porphyrin molecule.
What molecule is important in the formation of the heme portion of the hemoglobin molecule?
iron
What is the iron-containing portion of the hemoglobin molecule called?
The iron containing part of hemoglobin is the 'heme' molecule.
How many polypeptide chains form the globin portion of the molecule?
4 polypeptide chains, each bound to a heme group to form hemoglobing
What does a molecule contain?
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.
What does hemogoblin do?
a red protein responsible for transporting oxygen in the blood of vertebrates. Its molecule comprises four subunits, each containing an iron atom bound to a heme group.(From THE Macintosh dictionary). a red protein responsible for transporting oxygen in the blood of vertebrates. Its molecule comprises four subunits, each containing an iron atom bound to a heme group.(From THE Macintosh dictionary).
What portion of hemoglobin molecule binds oxygen?
Hemoglobin contains a heme group with an Iron ion attached to it. The iron is what binds to O2.
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 part of the hemoglobin molecule is recycled to form bile?
A portion of the heme group
