Select the correct statments regarding transport of molecules across the cell membrane.     Non-mediated transport is susceptible to saturation of transporter/channel proteins.     Channels and transporters need not use energy to transport solute down the concentration gradient.     The Na+/K+ antiport takes advantage of electrochemical gradients to exchange Na+ and K+ ions across the cell membrane.     Active transport via electrochemical gradients relies on the passive transport of one solute to transport a second solute against the concentration gradient.

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.
