Struggling with Bioelectricity Homework?

[fubag]

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.

Thanks!

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?
