,The substance HES (hydroxyethyl starch) is a plasma volume expander. In the year
2000, the International Ski Federation listed HES as a banned substance for
international competition. What is the likely explanation for why a skier in the
Olympics might use a plasma expander?
a) Increasing the plasma volume means that there is more space for the blood to
carry oxygen
b) Having more plasma means that the heart doesn't have to work as hard
c) If a skier had an abnormally high hematocrit due to blood doping, the hematocrit
could be reduced by taking a plasma volume expander
d) By increasing plasma volume, less lactic acid will be produced in the muscles
If a skier had an abnormally high hematocrit due to blood doping, the hematocrit
could be reduced by taking a plasma volume expander

d) It catalyzes the phosphorylation of a protein inside a cell
It catalyzes the phosphorylation of a protein inside a cell
A certain toxin blocks a G-protein coupled receptor whose effector protein is
adenylyl cyclase. Therefore, which of the following would not be produced by the
cell?
a) an ion channel

what would be the direction of the electrochemical force acting on potassium?
a) inward
b) outward
c) neither direction since there is no force
d) varied from cell to cell
e) varies based on the concentrations of potassium in the ICF and ECF
neither direction since there is no force
