Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

In mammalian cell intracellular concentration of following metal ions are as follows, Concentration of K+ is highest , i.e. , 100 mM Concentration of Na+ is 10 mM Concentration of Mg2+ is 0.5 mM. Concentration of Ca2+ is 10-100 nM. So the decreasing order of these ions concentration in mammalian cell will be, K+ > Na+ > Mg2+ > Ca2+. Hope this will be helpful. If you still have doubts fell free to ask.
