Biology Questions and Answers
- What are the other names
by which erythrocytes are
known? What is the function
of these cells?
Erythrocytesblood cells (RBCs), are also known as re or red corpuscles.d (^)
Red blood cells are responsible foxygen transport from the lungs to theor (^)
tissues.
- What is the name of the
molecule that transports
oxygen in red blood cells?
The respiratory cells is hemoglobin.pigment of the red blood
- What is the molecular
composition of hemoglobin?
Does the functionality of
hemoglobin as a protein
depend upon its tertiary or
upon its quaternary structure?
Hemoglobin is a molecule mapolypeptide chains, each bound to ade of four
iron-containing molecular group called a
heme group. So tfour polypeptide che molecule hains and four hemecontains (^)
groups.
As a protein comppolypeptide chains, thosed of association ofe functionality of
hemoglobin depends upon the integrityof its quaternary structure.
- On average what is the life
duration of the red blood
cells? Where are they
destroyed? What is the
destination of the heme
groups after the destruction of
hemoglobin molecules?
On average red blood cells live around
120 days. Twhere old red blood cells are he spleen is the main destroyorganed.
During the red blood cell dheme groups turn into bilirestruction thubin and thise
substance is then captured by the liver
and later of the bile.excreted in the bowels as part - What are the functions of
the spleen? Why is a total
splenectomy (surgical removal
of the spleen) compatible with
life?
The spleen has many functions: it
participatesblood cells; in it sp in the destruction of old redecialized leukocytes
are matured; it helps the renewal of the
hematopmarrow when necessary;oietic tissue of the bone it can act as a (^)
spongelike oblood from or rgan to retain or for the circulation.liberate
Total splenectomywith life as none of the functions of is not incompatible the (^)
spleen are vital and at the same time
exclusive of this organ.
