a) Use Ohm's Law

(V_(total )=iR)

and

i_(x)=0

(at rest) to derive the parallel\ circuit eqn:\

Vm=(E_(K)+((g_(Na))/(g_(K)))E_(Na)+((g_(C))/(g_(K)))E_(Cl))/(1+((g_(Na))/(g_(K)))+((g_(Cl))/(g_(K))))

\ b) Use the derived equation above to calculate the resting membrane\ potential if:\

E_(K)=-84mV,g_(K)=0.57\\\\mu mho\ E_(Na)=+48mV,g_(Na)=0.11\\\\mu mho\ E_(Cl)=-53mV,g_(Cl)=0.32\\\\mu mho

\ c) To what value must

g_(Na)

increase to make membrane\ potential

+40mV

if all else stays the same?\ GOOD LUCK!!\ and be sure to show your work.

4. a) Use Ohm's Law (Vtotal=iR) and ix=0 (at rest) to derive the parallel circuit eqn: Vm=1+(gNa/gK)+(gCl/gK)EK+(gNa/gK)ENa+(gCl/gK)ECl b) Use the derived equation above to calculate the resting membrane potential if: EK=84mVENa=+48mVECl=53mVgK=0.57mhogNa=0.11mhogCl=0.32mho c) To what value must gNa increase to make membrane potential +40mV if all else stays the same?
