Describe the structure of mitochondria with special reference to its membrane covering?

Mitochondria- it is called the powerhouse of cell synthesize ATP. It is a rod-shaped cell consisting of a number of cells in a small number of cells. They are able to make their own protein. They have two membrane coverings:

• The outer membrane- it is very porous, and it covers the surface of mitochondria. These are made up of phospholipid layers. The space between the outer and inner membrane is called the intermembrane space.


• The inner membrane- it has many folds call Christie they are meant to increase the surface area of the membrane so that inner membrane can hold proteins involved in the electron transport chain. This membrane is highly permeable to ions.


• The diagram is shown below:
