Explain the molecular mechanism of oxygen transport from the
mother to the fetus. How would transfer be affected if the fetus
has sickle-cell anemia? In your answer explain the molecular
mechanism of oxygen binding to sickle-cell and fetal
hemoglobin.
Gas Transport in the Blood. Efficient oxygen exchange requires
the reversible binding of oxygen to hemoglobin. Describe the
relationship between the partial pressure of oxygen in the blood
and the oxygen saturation of hemoglobin. Include a labeled figure
that clearly shows this relationship. Then, explain in detail the
significance of the relationship by discussing what is seen in
“average” body tissues and tissues that are metabolically active
(name them). Then, explain in detail the significance of the
relationship with respect...

people with sickle cell anemia have deformed red blood cells
that cant properly transport oxygen to cells. compared to a healthy
human, sickle cell patients would be mostly defective in?
a) osmosis
b)ATP production
c) glycolysis
d) fermentation
Explain the general mechanism for the simultaneous transport
of Na+ and K+ by the Na+/K+ ATPase (aka. Na+/K+ pump)
describing:
The result of this transport on the concentrations of Na+ and
K+ inside and outside of the cell
How the binding of Na+ and K+ are related to the conformation
changes on the protein
We discussed F-type pumps, which can also function in the
reverse direction (i.e. ATP synthase). Explain how this protein can
function both as a pump and...
which of the following cell transport mechanism requires a
transport protein, but not energy?
A- facilitated diffusion.
B- osmosis
C- active transport.
D- diffusion.
E- secondary active transport.
