Facilitative transporter ___________(a) Helps in facilitated diffusion

1.	Facilitative transporter ___________(a) Helps in facilitated diffusion(b) Changes conformation(c) Transports molecules passively(d) Changes conformation, transports molecules and facilitated diffusionI got this question in an interview for internship.This is a very interesting question from Movement of Substances Across Cell Membranes topic in chapter Cellular Membranes of Cell Biology
Answer» The correct answer is (d) Changes conformation, TRANSPORTS molecules and facilitated diffusion Easy explanation: Facilitated diffusion is a method by which molecules are diffused across the cell MEMBRANE with the help of an intermediate protein called facilitative transporter. The DIFFUSING substance binds selectively to this membrane-spanning protein that facilitates in diffusion PROCESS. It undergoes conformational change, exposing the solute to the other surface of the membrane.
