MULTIPLE CHOICE QUESTION Which of the following is FALSE about the components found in the plasma membrane? Some membrane proteins have carbohydrate chains attached to them that helps them aid in cell recognition. Integral proteins are sometimes considered transport proteins. Cholesterol helps to maintain flexibility and stability. The layers of phospholipids are arranged so that the heads face inward (interacting with eachother) and the tails face outward (interacting with the environment).

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.
