Difference between Simple Diffusion and Facilitated Diffusion

Difference between Simple Diffusion and Facilitated Diffusion

Difference between Simple Diffusion and Facilitated Diffusion are in tabular form below –

No.

Simple Diffusion

Facilitated Diffusion

Definition

1. A type of passive transport where transport of molecules across plasma membrane takes place, this is known as Simple Diffusion. A type of passive transport where transport of molecules across plasma membrane takes place and the transport occurs with the help of transport proteins, this is known as Facilitated diffusion.

Takes place through

2. This type of diffusion takes place through phospholipid bilayer. This type of diffusion takes place through transmembrane proteins.

Transportation

3. Transportation of small molecules occurs in the simple diffusion. Transportation of both small and large molecule occurs in the facilitated diffusion.

Examples

4. Examples include gases diffusion across respiratory membrane. Example include cotransport of sodium with sugars.

Polar or Non-polar

5. In the simple diffusion, non-polar particles are transported. In the facilitated diffusion, polar particles are transported.

Cell membrane/Facilitator membrane

6. This process takes place through cell membrane. This process takes place through specific facilitator membrane.
