The concentration of potassium ion on either side of the neuronal cell membrane while it is at rest is determined by __________________.
 | |
 |
the averaged interaction of the forces induced by both the concentration gradient and electrostatic pressure; |
 |
an active transport mechanism called the sodium-potassium pump; |
 |
an active transport mechanism called the potassium transport gate or channel; |
 |
both a and b are correct; |
 |
both a and c are correct; |
INCORRECT - Potassium transport gates or channels use passive, not active, transport mechanisms in their role of maintaining potassium gradients.
