The resting potential of a neuron is due to all of the following except: A) potassium being at a higher concentration inside the cell than out. B) sodium being at a higher concentration outside the cell than in. C) cells being more permeable to potassium than to sodium. D) the cytosol containing large molecules having a net negative charge. E) the sodium/potassium pump transporting 3 Na⁺ into the cell for every 2 K⁺ out.

Question

Quizplus · Accepted Answer

The sodium/potassium pump actually transports 3 Na⁺ out of the cell and 2 K⁺ into the cell, not the other way around. This helps maintain the resting potential by keeping the inside of the cell more negative compared to the outside.
