Question

What is facilitated transport?

Answer 1

Facilitated transport means "easy" transport of bigger molecules across the membrane via proteins.

Explanation:

Since bigger and hydrophilic molecules cannot pass across the membranes by diffusion from the phospholipids, these molecules like `Cl^-` , `Na^+` and many more travel across the membrane by facilitated diffusion. It is also a passive process. It is same as diffusion but through a channel or path to make the transport more easier.
