Ch (3 ptsy You are patcn-ciamping a cell. wnue noiaing tne neuron at airrerent membrane potentials, you observed the current recordings below. -10 mV m -50 mV a. (1 pt) How many channels does your patch likely contain? (2 pt) Given the recordings above, what is the reversal potential for the channel? Explain your reasoning in 1 sentence. b.

Explanation / Answer

Answer.

a) there are five ion channels as per the graph.

b) in the reversal potential a given neurotransmitter causes no net current flow of ions.

So as per the graph -10mv is the resting potential.
