One that blocks potassium and calcium channels

One that blocks sodium and potassium channels

One that blocks chlorine channels

One that blocks sodium channels

Answer 15

One that blocks potassium and calcium channels

Question 16

Using the voltage clamp to change the cell membrane potential of a neuron from -70.0 mV to -5.0 mV should cause:

A curent that indicates a large amount of sodium briefly entering the cell

A current that indicates that sodium continues to enter the cell as long as the membrane potential is set to -5 mV

A current that indicates a large amount of sodium briefly leaving the cell

No change in sodium current cross the cell

Answer 16

A current that indicates a large amount of sodium briefly entering the cell.
