Concept explainers

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.

For fusion of a vesicle with its target membrane tooccur, the membranes have to be brought to within 1.5 nmso that the two bilayers can join (Figure Q13–1). Assum-ing that the relevant portions of the two membranes at thefusion site are circular regions 1.5 nm in diameter, calcu-late the number of water molecules that would remainbetween the membranes. (Water is 55.5 M and the volumeof a cylinder is πr2h.) Given that an average phospholipid occupies a membrane surface area of 0.2 nm2, how manyphospholipids would be present in each of the opposingmonolayers at the fusion site? Are there sufficient watermolecules to bind to the hydrophilic head groups of thisnumber of phospholipids? (It is estimated that 10–12 watermolecules are normally associated with each phospho-lipid head group at the exposed surface of a membrane.)
