Facilitated Diffusion: Structural Characteristics

APBIO-EV8G2F

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

A distinction between the process by which an enzyme converts substrate to product and facilitated transport is

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.
