Which of the following interactions between electrical and chemical gradients does not lead to the establishment of a neuron's resting potential?
A)Chemical and electrical forces both favor sodium ions entering the cell.
B)Electrical forces push sodium ions out of the cell.
C)Chemical forces tend to drive potassium ions out of the cell.
D)Potassium ions are attracted to the negative charges inside the cell.
E)Potassium ions are repulsed by positive charges outside the cell.

Question

Quizplus · Accepted Answer

The establishment of a neuron's resting potential requires a balance between chemical and electrical gradients. Option B describes a situation where the electrical gradient counteracts the chemical gradient, which does not contribute to the establishment of resting potential. The other options describe situations where the electrical and chemical gradients work together in establishing the resting potential.
