What happens to the membrane potential when the net current of Na+ ions inflowing and K+ ions outflowing have the same magnitude?
What happens to the membrane potential when the net current of Na+ ions inflowing and K+ ions outflowing have the same magnitude?
- The membrane potential becomes more negative
- The membrane potential remains unchanged (correct)
- The membrane potential becomes more positive
- The membrane potential becomes unstable
If there is a net outflow of K+ ions, what effect does it have on the membrane potential?
If there is a net outflow of K+ ions, what effect does it have on the membrane potential?
- Stabilizes the membrane potential
- Makes the membrane potential more positive
- Makes the membrane potential more negative (correct)
- Has no effect on the membrane potential
What is the effect of a net inflow of Na+ ions on the membrane potential?
What is the effect of a net inflow of Na+ ions on the membrane potential?
- Makes the membrane potential more negative
- Stabilizes the membrane potential
- Makes the membrane potential more positive (correct)
- Causes membrane depolarization
