Consider a motor neuron: Diameter = 100 um Permittivity of vacuum = 8.85 x 10-12 Farad/m Dielectric constant of plasma membrane = 8 Faraday's constant = 96,500 coulombs/mol Cell osmolarity = 290 mOsM; estimate 50% are positive ions What percentage of the positive ions within a cell need to cross the membrane to create a -80 mV Em? Hints: Find how much charge is needed to generate Em using Q=C*V (as discussed in class). Convert the charge (coulombs) to moles...
