A researcher measured the concentration of K+ and S04- inside pea root cells (Ci) and in the surrounding medium (CO). The table below shows the results. She/He also measured the membrane potential (E E), which at 25C was 110 mV. - Ion K+ S04- Conc. in medium (mM) (CO) Root cell conc. (mM) (C) 1.25 90 0.25 9.5 Using the Nernst equation (RT In (Cj/Cj) = zF (E - E)), determine which of these two ions is close to passive equilibrium between the cells and the medium. For the calculations, the value of RT/F is equal to 25.8 mV, z is the charge of the ion. (Show the calculations that support your answer)
