Membrane structure and transport.

Explains how a mixture of sugar-salt-water works to prevent dehydration and electroclyte loss. the video begins with a real-life example of an infant suffering with diarrohoea being prescribed oral rehydration therapy; shows how sugars, amino acids, and certain irons are moved across the plasma membrane by transport proteins.
