How is facilitated diffusion different from passive transport?

Answer 1

Mediated Transport has an extra step of binding to a carrier protein, while Passive transport does not bind to a protein. Both of them however, move along the concentration gradient (High--> Low)

Answer 2

• Diffusion is simply the movement of solute from an area of greater concentration to lower concentration.
• Passive transport is the transport of molecules that do not require energy. Diffusion and osmosis are examples. Facilitated diffusion also falls into this category.
• Active transport is the transport of molecules that requires energy. Phagocytosis, Pinocytosis, as well as endocytosis and exocytosis all falls under this category.

Answer 3

Facilitated diffusion is a type of passive transport that involves the movement of molecules across a cell membrane with the help of specific transport proteins. In contrast, passive transport includes all methods of moving molecules across a membrane without the input of energy, including facilitated diffusion as well as simple diffusion and osmosis.

Answer 4

Facilitated diffusion is when substances use proteins to diffuse in or out. However with the other passive transport processes is accomplised by diffusion itself.

Answer 5

diffusion is through air, but osmosis is through water.
