Because of its fluid nature, water allows structures in a cell to disperse evenly to create a homogeneous spread. Water is needed for most of the reactions that take place in a functioning cell. Electrolytes (1%) when electrolytes dissolve they split into charged particles. Electrolytes facilitate many of the chemical reactions that occur in a cell.

Proteins are substances that cells manufacture for release. Proteins determine what kind of reactions take place.
