QUESTION 4 Suppose a neuron membrane has a specific capacitance (i.e. capacitance per unit area) of 10° F/m². Also suppose there are 3 x10 Na voltage-gated channels per m² allowing 200 Na ions to flow through each channel in 1 ms. Assuming no other changes occur during this time: a. Find the amount of charges (per area) that accumulate on the membrane 1 ms, after these channels open. Your answer: Answerl Coulomb/m² b. Find the change in the membrane potential (voltage) 1 ms after these channels open. Answer in the unit of mV. Your answer: Answer mV
