Intestinal epithelial cells pump glucose into the cell against its concentration gradient using the Na*-glucose symporter. Recallthat the Na+ concentration is significantly higher outside the cell than inside the cell. The symporter couples the "downhill"transport of two Na+ ions into the cell to the "uphill" transport of glucose into the cell.If the Na+ concentration outside the cell ([Na* lout) is 147 mM and that inside the cell ([Na+]in) is 17.0 mM, and the cellpotential is -54.0 mV (inside negative), calculate the maximum energy available for pumping a mole of glucose into the cell.Assume the temperature is 37 °C.AG gluckJmolWhat is the maximum ratio of [glucose]in to [glucose] outthat could theoretically be produced if the energycoupling were 100% efficient?1.132.3 × 10-48.364300
