$\text{Common Data Questions}$

$\text{Common Data for Questions 48 and 49}$:

In a muscle, the extracellular and intracellular concentrations of ${Na^+}$ are $\text{150 mM}$ and $\text{12 mM}$, and those of ${K^+}$ are $\text{2.7 mM}$ and $\text{140 mM}$, respectively. Assume that the temperature is ${25^0C}$ and that the membrane potential is -60 mV, with the interior more negatively charged than the exterior. ($\text{R = 8.314 J}$ ${mol^{-1}}$ ${K^{-1}}$; $F = 96.45$ $kJ$ ${mol^{-1}}$ ${v^{-1}}$)

The free energy change for the transport of two ${K^+}$ into the cell is

  1. $\text{+8.0 kJ/mol}$
  2. $\text{+11.6 kJ/mol}$
  3. $\text{+19.6 kJ/mol}$
  4. $\text{+31.2 kJ/mol}$
