Question

Quizplus · Accepted Answer

At rest, a neuron's plasma membrane is most permeable to potassium ions (K+), allowing them to flow more freely in and out of the cell compared to other ions. This permeability is crucial for maintaining the resting membrane potential. Sodium (Na+), large proteins, and chloride ions (Cl-) have restricted movement across the membrane in a resting neuron.
