5. (1pt) Glucose is pumped into an animal cell by a symporter powered by simultaneous entry of Na+ . What is the ratio of glucose concentration outside and inside cells under typical cellular conditions? Assume that external [Na+ ] = 140 mM, internal [Na+ ] = 12 mM and a membrane potential = −60 mV.

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...

1 In the absence of oxygen, cells consume glucose at a high, steady rate. When oxygen is added, glucose consumption drops precipitously and is then maintained at the lower rate. Why is glucose consumed at a high rate in the absence of oxygen and at a low rate in its presence? 2 In the following diagram showing the distribution of thermal energy in a population of substrate molecules, the energy thresholds indicated by numbers represent ...
