What is hemoglobin 4 heme, 4 iron, 4 globins
composed of?
What disorder does a Porphyria
defect in heme synthesis
lead to?
, Deficiency in the enzymes of the porphyrin
pathway leads to insufficient production of heme.
Porphyria The principal problem in these deficiencies is the
accumulation of porphyrins, the heme precursors,
which are toxic to tissue in high concentrations.
Methemoglobin is a form of hemoglobin that
contains ferric [Fe3+] iron and has a decreased
ability to bind oxygen. However, the ferric iron has
What is methemoglobin?
an increased affinity for bound oxygen. When
methemoglobin concentration is elevated in red
blood cells, tissue hypoxia can occur.
What is the function of To keep iron in the ferrous state
the enzyme
methemoglobin-
cytochrome C
reductase in a red
blood cell?
What product is formed Methemoglobin
when ferrous iron of
hemoglobin is oxidized
to the ferric state?
, A stable complex of carbon monoxide and
hemoglobin that forms in RBCs when carbon
monoxide is inhaled or produced in normal
What is metabolism. Large quantities of it hinder delivery
carboxyhemoglobin? of O2 to the body. Tobacco smoking (through
carbon monoxide inhalation) raises the blood
levels of
COHb by a factor of several times from its normal
concentrations.
Which hemoglobin has a Carboxyhemoglobin
200 times greater
binding capacity for the
hemoglobin molecule
than oxygen?
Which hemoglobin Sulfhemoglobin -- makes blood incapable of
derivative causes carrying oxygen.
irreversible changes in
RBCs?
Which of the following Hb-S
hemoglobins is NOT
normally present in a
normal adult?
Which embryonic Hb-F
hemoglobin is normally
found in newborns?
