006 Donnan Equilibrium and Driving Force

The video tutorial explains the Donnan equilibrium, membrane potential, and the driving force affecting ion movement. It begins with an introduction to the Donnan equilibrium, followed by a detailed explanation of membrane potential and its significance. The tutorial then delves into the Donnan equilibrium, using sodium ions as an example to illustrate how ions move in and out of cells. The concept of driving force is introduced, explaining how it influences sodium ion movement and membrane potential. The video concludes with a review of the key concepts discussed.

What is the definition of membrane potential?

Explain the concept of Donnan equilibrium.

What causes sodium ions to move into the cell?

How does the membrane potential affect the movement of sodium ions?

What happens to sodium ions when the membrane potential is far from its equilibrium potential?
