Astudent postulated that the sodium pump directly causes action potentials along neurons. is this hypothesis reasonable? a) no; action potentials result in increased permeability of the plasma membrane to sodium. b) no; the myelin sheaths of neurons prevent movement of ions across the plasma membranes of the neurons. c) yes; sodium is transported out of neurons during action potentials. d) yes; action potentials are accompanied by the hydrolysis of atp.
