The resting potential of a neuron is maintained because:
A)the positively charged potassium ions are too small to pass through the cell's membrane
B)the negatively charged sodium ions are too small to pass through the cell's membrane
C)the negatively charged protein molecules are too large to pass through the cell's membrane
D)the positively charged chloride ions are too large to pass through the cell's membrane

Question

Quizplus · Accepted Answer

The resting potential of a neuron is maintained because the negatively charged protein molecules present inside the neuron are too large to pass through the cell's membrane. This creates a negatively charged interior of the neuron and a positively charged exterior, thus maintaining the resting potential.
