Alternations surrounded by intracellular K+ concentration?
Hi,
I would like to know if any of you has an idea if surrounded by our body exist conditions under which potassium depleted cells (erythrocytes) could gain potassium ions?
Thanks a lot for any thought!
Answers:
The cell membrane possesses a sodium pump, which is continually pumping sodium ions out of the cell. At the same time a lesser amount of potassium is pumped inwards. This process is facilitated by insulin. As a result most of the body's potassium is stored inside the cell. Potassium losses are first from the fluids outside the cell, and only later is the intracellular store depleted. This loss does not take place from any specific group of cell, such as the erythrocytes, but from all the cells in the body. The treatment is to replace the potassium (either tablets or intravenously), when the potassium ions will diffuse and be pumped into the cell reasonably rapidly. There is no particular need to speed the process up near insulin. Source(s): 38 years in medicine.
