The Na –glucose symport system of intestinal epithelial cells couples the \"downhill\" transport of two Na ions into the cell to the \"uphill\" transport of glucose, pumping glucose into the cell against its concentration gradient. If the Na concentration outside the cell ([Na ]out) is 159 mM and that inside the cell ([Na ]in) is 23.0 mM, and the cell potential is -49.0 mV (inside negative), calculate the maximum ratio of [glucose]in to [glucose]out that could theoretically be produced if...

Consider a cell at steady state. The intracellular Cl- concentration is 10 mM, while the extracellular Cl- concentration is 108 mM when the chloride channels are closed. The electrical potential inside the cell is -65 mV, and the external potential is 0 mV. Calculate the electrochemical potential difference across the membrane. Assume R = 8.3144 J/mol K and T = 37C. When the chloride channels open, in which direction will the Cl- ions move?

Physiological pH inside of living cells is about 7.4. The total free concentration of phosphate inside of cells is about 1 mM. Phosphate exists in four different protonation states. Suppose that 100 ml of cellular extract is treated with 50 ml of 0.5 mM HCl. What is the final pH? [Assume that the HCl reacts only with the phosphate buffer in the cell extract.] Which form of phosphate is most abundant now?
