Passive Transport in Biology: Definition and Example

Definition:

-Passive transport is defined as the movement of molecule which does not require the energy for the process.

-In Passive transport molecule transport along with the concentration gradient. In Passive transport molecule transfer to high concentration to low concentration.

-Passive diffusion the molecule transport till the equilibrium at both sides achieved.

-Passive diffusion is rapid process.

-Small non polar molecule transport through the Passive transport.

     Following are the types of Passive transport

Types of Passive transport :

1. Diffusion

2. Facilitated Diffusion

3. Osmosis

4. Filtration

Example of  Passive transport:

-Movement of glucose molecule into the body is the example of the Passive transport. Glucose molecule

-The movement of the gases (Oxygen and carbon dioxide) between the outside environment and the lungs. Movement of the gases between the lungs and the blood.All movement is the example of the Passive transport. Transport of oxygen and carbon dioxide is the best example of the passive transport and the diffusion
