In this question, I'm asking you to connect lecture with 204 lab! The concentrations shown in the diagram are the concentrations of the solutions at the start of an experiment. a) At the start of the experiment, what is the total molarity of the solution in the dialysis bag and the cell? b) Describe the direction of diffusion (into the bag, out of the bag, or no net movement) at the beginning of the experiment for each molecule in the dialysis bag above: c) Describe the direction of diffusion (into the cell, out of the cell, or no net movement) at the beginning of the experiment for each molecule in the cell above (note: cell membrane is a phospholipid bilayer): 4. To function properly, cells must precisely regulate their internal ion concentrations. For example, the internal and external concentrations of Na and Cl are shown in the table below.
