Question
The diagram below shows the five main transport proteins that control the distribution of Na+ and K+ ions across the plasma membrane of an axon. Assume that the membrane is at resting potential---the membrane potential of the axon remains constant at about -70 mV. Drag the arrows onto the diagram to show the direction of Na+ (gray arrows) and K+ (red arrows) movement through each transport protein at resting potential. If no ions move through a transport protein at resting potential, leave that target blank.
I keep getting this wrong. I know that Potassium leaks out and Sodium Leaks in.
Explanation / Answer
Both of these are incorrect! Leave a and b blank becuase they are at resting potiential.
c Sodium out K in
d k out
e na in
