Bio416K Electrical Disequilibrium Practice Questions Answer the questions below about the cell diagrammed below. 1. Determine the absolute charge inside the cell (ICF)? _________ and outside the cell (ECF)? _________. Determine the relative charge of ICF with ECF assigned a value of zero)?   2.  Calculate the resting membrane potential difference for the cell in the diagram        above.  Assume the cell membrane is permeable only to Na +  and to K +  and that         the cell membrane K +  permeability is 40 times greater than that for Na + .  Use the         GHK equation (page 256-257; 294 of your textbook) to determine the resting        membrane potential difference for the cell. 3. What is the direction of the concentration gradient for Na + ? into the cell or out of the cell [Remember: solutes diffuse from high to low concentrations.] 4. What is the direction of the electrical gradient for Na + ? into the cell or out of the cell
