[6.1] If you could add channels to the membrane that make it permeable to peptides and water, what do you think would happen to the peptide and water molecules in the cell? [6.2] If, after adding those channels, you were to wait long enough for the system to equilibrate (i.e., reach a stable state in which the number and type of molecule in each compartment no longer changes much over time), about how many peptide molecules would you expect to find on the left side of the cell and how many on the right? How about the water molecules? Explain your reasoning.

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.
