Lipoprotein particles are relatively large, sphericalclumps of protein and lipid molecules (see Figure 3.18)that circulate in the blood of mammals. They are likesuitcases that move cholesterol, fatty acid remnants, triglycerides, and phospholipids from one place to anotherin the body. Given what you know about the solubilityof lipids in water, which types of lipids would you predict to be on the outside of a lipoprotein clump, bathedin the water-based fluid portion of blood?

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.
