# 10.24 Explain the significance of sodium, potassium, magnesium and calcium in biological fluids

Significance of sodium potassium, magnesium and calcium in biological fluids-

Sodium-

• It is mainly found in blood plasma and also in the interstitial fluid which surrounds the cell.
• $Na^{+}$ ions help in the transmission of nerve signals also for the regulating water in the plasma membrane.
• Also for the transport of sugars and amino acids into the cells.

Potassium-

•  These ions are highly present within cell fluids.
• Helps in activating many enzymes
• To produce ATP it oxidises the glucose molecule.
• Also helps in the transmission of nerve signals.

Magnesium and calcium-

•  Plays an important role in neuromuscular function (by magnesium), interneuronal transmission, cell membrane integrity and blood coagulation(by calcium)
• Mg helps in maintains normal blood circulation in our body.
