Question

Answer

Causes an increase in conductance for small cations.

Answer

Is positively charged and enters the cell in the same way as does Na +  during an action potential.

Answer

Causes an increase in conductance for Na +  ions only.

Answer

Triggers a voltage dependent conductance change just as occurs during generation of an action potential.

Answer

Causes an increase in conductance for both cations and anions.
