A drug called ouabain specifically inhibits the sodium-potassium pump present in neuron cells. Over time, this action of ouabain would 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 is responsible for maintaining a concentration gradient of sodium and potassium ions across the cell membrane. By inhibiting this pump, ouabain would eventually lead to the elimination of this gradient, as sodium and potassium ions would eventually reach an equilibrium. This would have various downstream effects on the neuron's ability to generate and conduct electrical impulses.
