Transcribed Image Text:

Intestinal epithelial cells pump glucose into the cell against its concentration gradient using the Nat-glucose symporter. Recall that 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 149 mM and that inside the cell ([Na*lin) is 21.0 mM, and the cell potential 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. What is the maximum ratio of [glucose]n to [glucose]ou kJ AGgluc = mol that could theoretically be produced if the energy coupling were 100% efficient? 3.5 x 10-4 O 7.96 2900 O 1.13 2 Intestinal epithelial cells pump glucose into the cell against its concentration gradient using the Nat-glucose symporter.
