You are studying a transport protein. It appears to bind temporarily to the molecule to be transported. During normal transport, no energy is expended. The addition of a particular molecule that closely resembles the normally transported molecule inhibits transport. An increase in the concentration of the normally transported molecule in the presence of a constant concentration of the inhibitor increases the rate of transport. What kind of transport is described?

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.
