Ionic permeability of the cell membrane (with a chemical unit Kobra3). P4120240

You can get the concept of:
Ionic permeability, artificial cell membrane, a dialysis tube, H + ions, O - ions, osmotic processes.

Principle:
The cell membrane regulates the transport of nutrients and water in the cell and therefore the conclusion of unnecessary products and water from it. This may occur as a passive, for example, through the osmotic process (differences in concentration), and active. In this experiment should be investigated selective capacity of artificial cell membranes (dialysis tube) for H + and O - ions.
