What is the function of the mitochondria ?

⠀

Mitochondria is also known as power house of the cell. The word mitochondria in singular is mitochondrian.

⠀

Mitochondria are tiny bodies in various shapes. (Cylindrical, spherical, rod shaped e.t.c)

⠀

The shape of mitochondria varies from (0.2 mm to 2mm).

⠀

Each mitochondrian is surrounded by double layer of membrane. The doublelayer is divided in two layers -

⠀

⠀⠀⠀⠀⠀⠀★ The inner membrane.

⠀⠀⠀⠀⠀⠀★ The outer membrane.

⠀

The inner membrane folds are known as cristae and this membrane is studded by small bodies often known as particles and oxysomes.

⠀

On the other hand the outer membrane is porous. The inner cavity of mitochondria ( matrix ) contain small sized ribosomes.

⠀

⠀

Mitochondria oxidise the carbohydrates and fats present in our cells.

⠀

This oxidation releases energy which is used in form of ATP (adenosine triphosphate).

⠀

ATP is generally known as energy carrier or energy currency of the cell.

⠀

This ATP synthesis the chemical compounds (DNA replication, RNA transaction, synthesis of proteins, lipids and carbohydrates).

⠀

Mitochondria also perform the function of mechanical work, as contraction of muscles.

Ithink the dna sequences may vary but the amino acid sequences are identical.
