Many biochemical reactions that occur in cells require relatively high concentrations of potassium ion (K+). The concentration of K+ in muscle cells is about 0.15 M. The concentration of K+ in blood plasma is about 0.0050 M. The high internal concentration in cells is maintained by pumping K+ from the plasma. How much work must be done to transport 1.0 mol K+ from the blood to the inside of a muscle cell at 37°C, normal body temperature?
When 1.0 mol K+ is transferred from blood to the cells, why do other ions have to be transported?
