Osmosis

In simple words, osmosis is the slow, gradual movement of a liquid through a membrane. But there are nuances to this process. For instance, there has to be an imbalance in the distribution of solute in the liquid on either side of the membrane, which has to be semipermeable. The liquid in the region with a lower solute concentration moves to the region with a higher concentration, thereby displacing the solution in the process. The objective is to equalize the concentration of molecules on both sides of the membrane; the displacement of liquid can be viewed as a byproduct of this equalization. Since there is no energy required to carry osmosis, it is considered a passive process.

How many copies of a protein need to be presentin a cell in order for it to be visible as a band on an SDSgel? Assume that you can load 100 μg of cell extract ontoa gel and that you can detect 10 ng in a single band by sil-ver staining the gel. The concentration of protein in cellsis about 200 mg/mL, and a typical mammalian cell has avolume of about 1000 μm3 and a typical bacterium a vol-ume of about 1 μm3. Given these parameters, calculatethe number of copies of a 120-kd protein that would needto be present in a mammalian cell and in a bacterium inorder to give a detectable band on a gel. You might try anorder-of-magnitude guess before you make the calcula-tions.
