In a neuron at rest,

Question

Quizplus · Accepted Answer

At rest, active transport is occurring in the form of the sodium-potassium pump, which actively moves sodium out of the cell and potassium into the cell. Therefore, option A is incorrect. Option B is also incorrect because the concentration gradient is such that there are more sodium ions outside the cell and more potassium ions inside the cell. Option C is not necessarily true since basic cellular processes still occur in a resting neuron. Option D is incorrect because the inside of a neuron is negatively charged as compared to the outside due to the uneven distribution of ions. Therefore, the correct answer is E: potassium ions are more concentrated inside the cell than outside.
