Mitochondria Lecture | The Cell Chapter 1 Year Biology Lecture by Student Point

Mitochondria are often described as the powerhouses of the cell because of their central role in the synthesis of ATP, a vital source of energy for the body. They are composed of a double membrane, intramembranous space, and matrix. Various mitochondrial types can be differentiated based on the inner membrane structure.

The structure and DNA of mitochondria resemble the structure and DNA of prokaryotes. Mitochondria are believed to have been prokaryotes originally that evolved into endosymbionts living inside eukaryotes

Mitochondrial membrane
There are two, highly specialized mitochondrial membranes that surround the mitochondrion. They provide the framework for the electron transport chain and ATP production.

Outer membrane
Structure: smooth
Permeability: interspersed with pores, highly permeable for various molecules
