Based on Goldman-Hodgkin-Katz Equation: If pNa = pCl = 0, GHK equation reduces to Nernst Equation In squid, pK : pNa : pCl = 1.0 : 0.04 : 0.45 At 20(C, Vm = -62 mV In mammals, pCl is lower, pNa is lower, Thus Vm is lower, -80 to –90 mV Concepts in Electricity Water Flow Electricity Neurons
WebMay 7, 2024 · 1. The GHK voltage equation also known as just "Goldman equation" is always valid for determining the voltage at which the net current is zero, given internal/external ion concentrations and their permeabilities. This includes times during the action potential, though the result you get from GHK will be changing faster than the … The GHK voltage equation for monovalent positive ionic species and negative: This results in the following if we consider a membrane separating two -solutions: It is "Nernst-like" but has a term for each permeant ion: • = the membrane potential (in volts, equivalent to joules per coulomb) • = the selectivity for that ion (in meters per second)
