Homework Help: Bioelectricity homework problem

  1. Sep 15, 2007 #1
    I have received a homework document from one of my professors.

    However, I am having difficulty answering some of the questions, since the diagram seems so awful to understand.

    You can find the document here. http://docs.google.com/Doc?id=dcnj7bph_2fnmnzt

    For question # 1 and 2 I put respectfully the number given, because I couldn't figure any other way to figure that out.

    For question # 4 I put diffusion, but I am wondering if electrical flux will also suffice?

    For question #5 I put J(diffusion) = -D {dC/dx} determined by Flick's Law

    For question #6 I put equilibrium and the behavior of charged ions will eventually halt the movement of K+ ions. However, it is asking for a process, so I am not too sure about this one.

    For question #7 it is asking the name of the process...a bit confused.

    For question # 8 I answered they will be evenly distributed? once again not too sure

    Will continue as I work through the problem.

    Any feedback/help will be most deeply appreciated.

    still confused, unable to determine relative ion concentration for K+ and Cl- given information in diagram...

    Later on, this screws my Nersnt Equation and Goldman's equation.

    Can anyone help?
