A) both positive and negative ions are concentrated inside the neural membrane

C) negative ions are concentrated outside the neural membrane while positive ions are concentrated inside the membrane
D) both positive and negative ions are concentrated outside the neural membrane

Question

Quizplus · Accepted Answer

When a neuron is polarized, positive ions such as sodium (Na+) and potassium (K+) are concentrated outside the neural membrane while negative ions such as chloride (Cl-) and protein anions are concentrated inside the membrane. This creates an electrical charge difference across the membrane, with the inside of the neuron being negatively charged relative to the outside.
