❤.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.
