Assume that a membrane permeable to Na+ but not to Cl- separates two solutions. The concentration of sodium chloride on side 1 is higher than on side 2. Which of the following ionic movements would occur? a. Na+ would move until its concentration gradient is dissipated (until the concentration of Na+ on side 2 is the same as the concentration of Na+ on side 1). b. Cl- would move down its concentration gradient from side 1 to side 2. c. A membrane potential, negative on side 1, would develop. d. A membrane potential, positive on side 1, would develop. e. None of the preceding is correct.
Suppose that the concentration of CI outside the cell is 100 and inside the cell is 10 mmol/liter. The Nernst equation at 20°C is: Eton = 58 millivolts/z- [10810 (m)] [lonlin You set the membrane voltage at 0 millivolts using a voltage clamp, and measure membrane current. If Cl is the only ion crossing the membrane, you would expect to see: Onegative charges flowing into the cell negative charges flow out of the cell 0 current the membrane hyperpolarizes (becomes more negative)
Various chemical methods can be used to permeabilize or lyse cells including the use of enzymes. List three important factors to consider when developing a lysis method using enzymes. Estimate the osmotic pressure drop across the membrane of an animal cell in a 0.10 M NaCl solution, assuming that the internal total solute concentration is 0.36 osM and temperature is 30.0°C. Do you think that this pressure drop would lyse cells? Why or why not?
Here's one experimental approach to finding out how rapidly a membrane transporter can move its solute into the cell: combine biochemical information about how much solute accumulates in the cell over time with structural information about how many transporters are on the surface of the cell. You are studying a spherical eukaryotic cell that has a diameter of 20 um and is engaged in glycolysis. Its energy source is glucose, which it is taking up from its environment via Na/glucose symporters distributed throughout the surface of its plasma membrane. By briefly adding an inhibitor of all glucose breakdown, you are able to determine that glucose accumulates in the cell at the rate of (5.000x10^1) µM/hr. Based on this number, how many umoles of glucose must be entering the cell per hour? (Assume that one-half of the volume of the cell is composed of organelles, and thus not available for diffusion of glucose). Put your final answer in umol/hr.

What is the free energy change for the transport of calcium ions (Ca++) across a membrane from a region (left) where the concentration is 50 micromolar to a region (right) where the concentration is 50 micromolar? A membrane potential of 60 mV exists across the membrane where the right side is more negative than the left side. The temperature is 25 C.
