1.	GLUT1 is an example of ______________(a) Channel protein(b) Facilitative transporter(c) Active transporter(d) Lipid-anchored proteinI got this question during an interview.This intriguing question originated from Movement of Substances Across Cell Membranes in section Cellular Membranes of Cell Biology
Answer» Correct choice is (b) Facilitative transporter For explanation I WOULD say: Humans consist of membrane-spanning proteins that HELP in the TRANSPORT of glucose molecules through the cell membrane. These molecules have five ISOFORMS from GLUT1 to GLUT5. It facilitates the diffusion of glucose from the bloodstream into the cell through facilitated diffusion.
