Ans.1)  class="MsoNormal" style="margin: 0in 0in 10pt">Electrolytes are the substances that produce ions in the solution. Some of these ions are essential for normal functioning of body.

Sodium (Na⁺) & Potassium (K⁺):

Major proportion of Sodium is present in extracellular fluid i.e. outside of cell and Potassium is present in inside of cells.

1. Sodium-potassium pump i.e. Na⁺/K⁺ pump transport 3Na⁺ out of the cell and 2 K⁺ inside the cell. It regulates the volume of the cell. 

2. Export of sodium from the cell provides the driving force for the import of glucose, amino acids and other nutrients into the cell by use of the sodium gradient.

3.  Sodium is critical in generation of electrical signals in synapses & junctions of brain and nervous system.

4. An abnormal increase or decrease in concentration of potassium causes irregular heart beats.

Chloride (Cl^-):

Chloride is the major anion found in the fluid outside of cells and in the blood.  An abnormal increase or decrease in concentration of potassium can lead to heavy sweating and kidney disorders.

Bicarbonate(HCO₃^-):

The bicarbonate ion acts as a buffer to maintain the normal levels of pH in blood and other fluids in the body.
