Question: a neuron has a resting membrane potential of 80 mv...

Question details

A neuron has a resting membrane potential of -80 mV.

Opening:

One calcium channel causes a change in membrane potential of +5 mV.

One chloride channel causes a change in membrane potential of -3 mV.

When the post-synaptic neuron (above) is at resting potential, how many channels of which kind would need to open to generate an action potential?
