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?

A

Solutes are able to undergo transport without chemical modification.

B

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

C

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

D

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