The inside of the cell membrane is negative, not only due to the active transport system but also because of__________________, which remain negative due to intracellular pH and keep the inside of the cell membrane negative.

Why does a nerve's action potential increase slightly when you add 1.0 V to threshold voltage and stimulate the nerve?

Why does the addition of sodium chloride elicit an action potential?

Hypothesize what type of animals would have the fastest conduction velocities?

Why does the addition of sodium chloride elicit an action potential?

While the sodium-potassium pump is pumping sodium out of the cell and potassium into the cell, these ions are leaking back where they came from by diffusion. By adding sodium chloride, a more-than-normal amount of sodium will diffuse into the nerve, causing the resting membrane potential to reach the threshold value, bringing about a membrane depolarization.
