A drug called ouabain specifically inhibits the sodium-potassium pump present in neuron cells. Over time, what would this action of ouabain cause?
A) the inside of the neuron to become more negative
B) repolarization
C) elimination of a concentration gradient
D) more potassium to be transported into the neuron

Question

Quizplus · Accepted Answer

The sodium-potassium pump helps maintain a concentration gradient by moving 3 sodium ions out of the cell and 2 potassium ions into the cell. Inhibiting the pump with ouabain would cause an elimination of this gradient over time as the ions become more evenly distributed, leading to cellular dysfunction.
