Question

Which substance uses a carrier protein to cross the plasma membrane by facilitated diffusion?

Answer 1

Carrier Protein :

These are the cell membrane proteins that help in facilitated diffusion and active transport of substances in and out of the cell.

Facilitated Diffusion:

1. Facilitated Diffusion is a passive transport of Ions and molecules across the plasma membrane along the concentration gradient.
2. It is a selective process that's why the membrane allows only selective ions and molecules to pass through it.
3. Glucose uses a carrier protein to cross the plasma membrane by facilitated diffusion.
4. common glucose transporters which help in glucose transfer are GLUTs.
5. GLUTs are integral membrane protein
