A cells membrane potential is -80mV. A neurotransmitter binds to a magnesium ion channel and opens that channels gate. Magnesiums equilibrium potential is 0mV and magnesium is a cation.
A. How could you classify the magnesium ion channel based on its gating mechanism?
B. Which direction is the net flux of magnesium through the channel?
C. How does the movement of magnesium through the channel affect the ions charge (membrane potential)?
