Question

How are the proteins used for active transport different from those used for facilitated diffusion?

Answer 1

The proteins that carry out active transport move only the largest molecules. Facilitated diffusion is passive transport in which larger molecules are transported through trans-membrane proteins and requires no energy

Answer 2

carry specific molecules one way across the membrane. use ATP to carry molecules across the membrane. carry molecules against the concentration gradient (low-high). much faster and more efficient than facilitated diffusion.
