Potassium ions function
WebPotassium is an essential micro-mineral in the body. The potassium ions present in blood control nerve function and heart rate. 98 percent of the potassium in the body is found inside the cells. Appropriate potassium intake (100 milligrams per day) is required for the healthy functioning of the body systems. WebThe sodium-potassium pump is a trans-membrane protein that helps establish the resting membrane potential of cells, particularly neurons. In a process that requires ATP, the pump moves three sodium ions out of the cell for every two potassium ions it brings in. This contributes to the electric potential difference between the inside and outside ...
