Answer:
Competition
Explanation:
Transportation of some molecules can not be through simple diffusion due to their size or other factors.
Therefore carrier proteins known as transporters are needed to facilitate their transportation.
Transporters exhibit or demonstrate characteristics such as competition,
During competition, presence of a certain molecule decreases the transportation of another molecule.
When Uric acid transportation is decreased due to the presence of probenecid is a good example of competition.
It means that they are not like pre-set blueprints. They react differently according to changes in the environment.<span />
