There is 1 glossary search result for: Electrochemical driving force
Abbreviation:
VDFDefinition:
When an ion is not at its electrochemical equilibrium, an electrochemical driving force (VDF) acts on the ion, causing the net movement of the ion across the membrane down its own electrochemical gradient.The electrochemical driving force is generally expressed in millivolts and is calculated according the following equation:
VDF = Vm − Veq
where VDF is the electrochemical driving force, Vm is the membrane potential, and Veq is the equilibrium potential.
