What is Passive Transport?

What is Passive Transport?

The passage of molecules of different substances through the plasma membrane from a region of high concentration to low concentration, i.e., along a concentration gradient, is known as passive transport.

In passive transport, no energy is required and molecules move along the concentration gradient.

The passive transport of metabolites can be accomplished by anyone of the following Methods.

1. Simple diffusion 2. Facilitated diffusion

What is simple diffusion? 

Transport of metabolites across the membrane along the concentration gradient and without the carrier molecule is called simple diffusion.

The molecules of substances pass through the gaps or channels of membrane transport proteins, called channel proteins.
