A carrier protein transfers a solute across the phospholipid bilayer via facilitated diffusion and behaves much like an enzyme-substrate reaction.

Which of the following is a distinction between the process by which an enzyme converts substrate to product and facilitated transport?


Solutes are able to undergo transport without chemical modification.


Solutes are restricted to flow in one direction depending on the orientation of the carrier protein.


Solutes are directly transported without interacting with or influencing the conformational state of the carrier protein.


Solutes are transported whether or not there is a competitive or noncompetitive inhibitor present.
