Many biochemical reactions that occur in cells require relatively high concentrations of potassium ion $\left(\mathrm{K}^{+}\right) .$ The concentration of $\mathrm{K}^{+}$ in muscle cells is about 0.15$M$ . The concentration of $\mathrm{K}^{+}$ in blood plasma is about 0.0050$M .$ The high internal
concentration in cells is maintained by pumping $\mathrm{K}^{+}$ from the plasma. How much work must be done to transport 1.0 mole of $\mathrm{K}^{+}$ from the blood to the inside of a muscle cell at $37^{\circ} \mathrm{C}$ normal body temperature? When 1.0 mole of $\mathrm{K}^{+}$ is transferred
from blood to the cells, do any other ions have to be transported? Why or why not?
