Hello if someone could help me with this please much appreciated. Thank you
intestinal epithelial cells pump glucose into the cell against its concentration gradient using the Na+ -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+]out) is 141 mM and that inside the cell ([Na+]in) is 19.0 mM, and the cell potential is -52.0 mV (inside negative), calculate the maximum energy available for pumping a mole of glucose into the cell.
Please Assume the temperature is 37 C
Also, what is the maximum ratio of [glucose]in to [glucose]out that could theoretically be produced if the energy coupling were 100% efficient?
