How hemoglobin affects red blood cells?

Answer 1

Hemoglobin is a metalloprotein, which is a generic term for a protein that contains a metal iron cofactor. (A cofactor in biochemistry terms is a non-protein chemical compound that is bound to a protein and is vital for the protein's biological activity.)

Answer 2

The name hemoglobin is derived from the words heme and globin, reflecting the fact that each subunit of hemoglobin is a globular protein with an embedded heme group. This is what attracts oxygen to the entire molecule. As absence of iron decreases heme synthesis, red blood cells in iron deficiency anemia lack the red hemoglobin pigment and are smaller than normal.

Answer 3

Iron deficiency gives rise to a microcytic anaemia, that is to say there is less haemoglobin circulating (spell it properly!) and the MCV of the cells is reduced, i.e. they have less volume.

Answer 4

Hemoglobin is the essential protein that is in all red blood cells. Without hemoglobins, cells would have no purpose.
