Generalizations of the Goldman-Hodgkin-Katz equation
WebThe Goldman-Hodgkin-Katz Equation. This song helps students understand the Goldman-Hodgkin-Katz (GHK) equation, which calculates a cell's membrane potential … WebThe Goldman-Hodgkin-Katz current equation (or GHK current equation) describes the current carried by an ionic species across a cell membrane as a function of the transmembrane potential and the concentrations of the ion inside and outside of the cell. Since both the voltage and the concentration gradients influence the movement of ions, … skippin scool bus
The enduring legacy of the “constant-field equation” in …
WebGoldman, Hodgkin and Katz furthered the study of membrane potential by developing the Goldman-Hodgkin-Katz equation to account for any ion that might permeate the … The Goldman–Hodgkin–Katz flux equation (or GHK flux equation or GHK current density equation) describes the ionic flux across a cell membrane as a function of the transmembrane potential and the concentrations of the ion inside and outside of the cell. Since both the voltage and the concentration gradients influence the movement of ions, this process is a simplified version of electrodiffusion. Electrodiffusion is most accurately defined by the Nernst–Planck equ… WebCalculate a cell's membrane potential from ion concentrations and permeances!
