The CFTR protein is a chloride channel in the cell membrane. Use your understanding of the biochemical properties/categories of amino acids and how they interact with membrane phospholipids to predict the distribution of charged/polar, and non-polar amino acids within the domains of CFTR listed below. Consider one category to include the charged amino acids and the polar amino acids and the other category to include the non-polar amino acids. For each domain, predict which category of amino acids is likely to be most abundant. Also, explain the rationale behind your prediction.

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.
