Question
Chapter 6, Problem 9aCP
Summary Introduction
To review:
The sodium and potassium equilibrium potentials.
Introduction:
Equilibrium potential is also called a reversal potential. The equilibrium potential is the potential during an open channel where the net flow in the channel is zero. The electrical potential difference across a cell balances with the concentration gradient of an ion. This is known as the equilibrium potential.
