When a nerve cell is stimulated, the cell membrane becomes ______ permeable to _______.

Question

Quizplus · Accepted Answer

When a nerve cell is stimulated, the cell membrane becomes more permeable to sodium ions. This results in an influx of sodium ions into the cell, leading to depolarization and generation of an action potential. Option A is incorrect because the cell membrane becomes more permeable to sodium and not chloride. Option B is incorrect because a decrease in chloride permeability would not lead to depolarization. Option D is incorrect because the cell membrane becoming less permeable to sodium would inhibit the generation of action potentials.
