Which describes one of the ways proteins behave in facilitated diffusion? a)they change membranes. b)they use atp. c)they change shape. d)they create channels..

Option D is correct.

D)They create channels.

Facilitated diffusion is the movement of molecules across the cell membrane of a cell through carrier proteins and protein channels. IN Facilitated diffusion no energy is required so it is called passive transport.

The molecules that can not directly diffuse across the membrane, they are transported through special channels and carrier proteins.
