Q. What causes the rapid change in the resting membrane potential that initiates an action
potential?
a. Potassium gates open, and potassium rushes into the cell, changing the membrane
potential from negative to positive.
b. Sodium gates open, and sodium rushes into the cell, changing the membrane
potential from negative to positive.
c. Sodium gates close, allowing potassium into the cell to change the membrane
potential from positive to negative.
d. Potassium gates close, allowing sodium into the cell to change the membrane
potential from positive to negative.
ANS: B
When the threshold is reached, the cell will continue to depolarize with no further stimulation.
The sodium gates open, and sodium rushes into the cell, causing the membrane potential to
reduce to zero and then become positive (depolarization).
Sodium is involved in creating the action potential, not potassium.
The sodium gate must be open, not closed.
The sodium channel must be open; this is not affected by a change in the potassium gate.
Q. A cell is isolated, and electrophysiology studies reveal that the resting membrane potential is
70 millivolts. The predominant intracellular ion is Na+, and the predominant extracellular ion is
K+. With voltage change, which of the following would result in an action potential?
a. K+ rushing into the cell
b. Na+ rushing into the cell
c. Na+ rushing out of the cell
d. K+ rushing out of the cell
ANS: A
With voltage change, potassium rushes into the cell.
