Explain the significance of sodium, potassium, magnesium and calcium in biological fluids.
Answers
Answer:
Sodium-
It is mainly found in blood plasma and also in the interstitial fluid which surrounds the cell.
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
❤.Significane of Na, K in biological fluids.
Na+ ions participate in the transmission of nerve signals.
Na+ ions regulate the flow of blood across the cell membrane.
Na+ ions resonsible for transport of sugars and amino acids into cells.
K+ ions are useful in activating enzymes.
K+ ions participate in the oxidation of glucose to produce ATP.
K+along with Na+ responsible for the transmission of nerve signals.
❤. signicicane of mg2+
mg2+ ions are concentrated in animal cells.
Enzymes like "phosphohydrolases'and 'phospho transferases'contains Mg2+ ions.
These enzymes participate in ATP reactions and release energy in the process Mg2+ forms a complex witg ATP
Mg2+is a constitute of chlorophyll, the green component of plants.
❤.Significance of ca2+
Used in teeths and bones.
used in cogulation of blood.
necessary for muscle contraction.
