Consider a state change from normal where there is an increase in...

Consider a state change from normal where there is an increase in sodium (Na+) in the extracellular fluid (ECF). 

 

1) Does the resting membrane potential (Vmrest) change in this condition, if so how?

 

(The graphs below are of millivolts vs. time. Any difference in height, duration, or thickness are just an outcome of drawing and not meant to represent a component of the answer)

 

The Vm rest normal in each graph is identical (-65mV)

a) resting membrane potential doesn't change

b) 

c)

2) What equation did you use to determine your answer?

What equation did you use to determine your answer?

a)no equation

b)Goldman - Hodgkin Katz (GHK) because this equation accounts for changes in concentration and permeability for all ions

c)Nernst Potential because this equation accounts for changes in concentration and permeability for all ions

d)Goldman - Hodgkin Katz (GHK) because this equation accounts for changes in concentration for one ion

e)Nernst because this equation accounts for changes in concentration for one ion
