Concept explainers

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.

SNAT2 (a membrane protein) determines the cell’s content of most amino acids. It acts as a symport (or co-transporter) of Na+ and amino acids. On the outside of the cell, the Na+ concentration is higher than the inside. The amino acid concentration on the inside of the cell is higher than the outside. When both Na+ and an amino acid bind to the SNAT2 membrane channel on the outside of the cell, there is a conformational change allowing the energy from electrochemical gradient of Na+ for the transport of the amino acid into the cell. a. Draw this scenario and label your representations of Na+, amino acids, SNAT2, and the membrane. b. What kind of transport is this, simple diffusion, facilitated, diffusion, active transport, 1o active transport, or 2o active transport? Explain your choice. Thanks
