Question
Jens Christian Skou won a Nobel in 1997 for discovering this P-type protein, which can be inhibited by ouabain and digoxin. For 10 points each:
[10m] Name this protein which is estimated to use up to anywhere from 20-40% of the brain’s energy by restoring the resting membrane potential in neurons.
ANSWER: sodium-potassium pump [accept Na+/K+ ATPase]
[10h] This hormone reduces serum potassium levels, which is believed to occur through increased translocation of the sodium-potassium pump at skeletal muscle cell surfaces.
ANSWER: insulin
[10e] These organisms contain two paralog proteins of the sodium-potassium pump, JY-alpha and Atp-alpha. Data from this model organism’s genome is hosted on the database FlyBase.
ANSWER: fruit flies [accept Drosophila melanogaster]
