Various types of vesicle coats have been implicated in membrane traffic pathways such as endocytosis, export from the ER to the Golgi, and transport between Golgi cisternae. But so far, no coat has been identified for the secretory vesicles that carry material from the Golgi to the plasma membrane. Do you think such a coat is likely to exist? Justify your answer.

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.
