Question

Write the functions of mitochondria

Answer 1

Mitochondria's functions :- Mitochondria are called the powerhouses of the                                               cell. The energy needed for different chemical activities required for life is released by mitochondria in the form of ATP (Adenosine triphosphate) molecules. ATP is called the energy currency of the cell. The body uses energy accumulated in ATP for forming new chemical compounds and for mechanical work. Mitochondria contain two membrane is quite porous whereas the inner membrane is deeply folded. these folds create a huge surface area of ATP-generating chemical reactions.

Mitochondria are unique organelles in the sense that they have their own DNA and ribosomes. Hence, mitochondria are able to prepare some of their own proteins.

Answer 2

Mitochondria:-

Mitochondria differ in shapes in different cells like cylindrical, rod shaped, spherical, etc. They are 6-10 times smaller than nucleus. They are also known as powerhouse of the cell. Mitochondria are present in the cytoplasm of all eukaryotic cells.

Function of mitochondria are as follows:-

i) Mitochondria play an important role in the process of respiration of cell.

ii) They are the respiratory centre of the cell. It releases energy in the form of ATP (Adenosine triphosphate).

iii) They become the energy source of the biological activities of the cell.

iv) They helps in synthesis of amino acids and steroids.

v) Due to presence of genetic material, they divides and genetic characters are transferred from one generation to another.
