Question

Structure of mitochondria

Answer 1

mitochondria are small , spherical or cylindrical organelles . a mitochondria is 2-8 micron long and about 0.5 micron wide . it is about 150 times smaller than the nucleus . there are about 100-150 mitochondria in each cell. when sending under the microscope , the mitochondria appear as oval or cylindrical dots in the cell . electron microscope reveals their unique structure in great detail. mitochondria are made up of a double membrane wall. the inner membrane of the wall protrudes into the interior in folds and forms structures called cristae . the space between cristae is known as the matrix. mitochondria are responsible for cellular respiration , a process through which the cell derives its energy to do the work . because of this mitochondria are also known as the power house of the cell . hope this helps u . please mark as the brainliest.

Answer 2

Structure of Mitochondria:  

 It is regarded as power house of cell as they contain enzymes necessary for oxidation of food and generation of ATP.

 Mitochondria have double membrane: outer membrane is porous while inner membrane is highly folded and selectively permeable.  

 Infoldings of inner membrane are called cristae.

Note: Cristae increase surface area for ATP generating chemical reaction (Electron Transport Chain).  

 Inner compartment is filled with a fluid called matrix. Matrix of mitochondria contains enzymes of Kreb’s cycle.

 Matrix has single circular DNA molecule and ribosomes (70S); hence they can make their own proteins. Therefore mitochondria are regarded as semi-autonomous cell organelle.

Oxysomes:

 These are also known as elementary particles or FO-F1 complex.  

 These particles are associated with inner membrane. F1 component of Oxysome lies towards inner chamber.

 Each particle consists of 3 parts: head, stalk and base piece.

 Oxysome represents ATPase enzyme which is concerned with ATP formation.
