Salt composition of a quiescent cell

Post by KARistanmickey » Thu May 09, 2019 7:45 am

Hello everyone,,
We were asked the following question in a test:

What would be the order (decreasing) of concentrations of the metal ions K+, Na+, Mg+2 and Ca+2 in a quiescent mammalian cell?

I wasn't able to figure out any changes that may arise during quiescence, so I answered:

K+ > Mg+2 > Na+ > Ca+2

Now that I think about it, perhaps not as much Mg+2 would be present inside the cell due to lower ATP demand?

Please help me out. Clearly my concepts aren't strong.
