Question

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.

Hello!!

_______________________________

⭕Mitochondria:

➡️ Mitochondria are cylindrical or sausage - shaped double membraned organelles distributed in the cytoplasm.

➡️ They are not visible under the microscope.

➡️ Thus, they are stained by vital stain Janus green to make them visible for observation.

➡️ Mitochondria show great degree of variability in their shape, size and number.

⭕Functions of Mitochondria:

➡️ Mitochondria are main site of aerobic respiration.

➡️ They are miniature biochemical factories where food stuffs or respiratory substrates are completely oxidised to carbon dioxide and water.

➡️ The energy liberated in the process is stored in the form of ATP.

➡️ These bring about the oxidation of carbohydrates, proteins and beta-oxidation of fats.

➡️ Energy produced in mitochondria helps to perform various energy requiring processes of the cell like muscle contraction, nerve impulse conduction etc.

➡️ Because of the formation of ATP mitochondria called powerhouse of the cell.
