Homework Help: Help!: Nernst and reversal potentials

  1. Oct 30, 2006 #1
    I know the following
    ion/inside cell/outside cell
    Cl- 5mM 150 mM
    K+ 130mM 5mM
    Na+ 20mM 140mM
    Ca2+ 10^-4mM 2mM

    How would I find the reversal potential for conductance equally permeable to sodium and potassium?
    How do I find the reversal potential for a conductance equally permeable to sodium, potassium, and chlorine?
    Also, how do I find the nernst potential for each ion at the below external and internal concentrations?
