Hey there!!!
Find your detailed description below!! ^_^

¤ Mitochondria :
• INTRODUCTION:
- It is typically a sausage shaped Or cylindrical cell organelle having a diameter of 0.2-1.0 micrometers ( avg. 0.5micrometer ) and length 1.0-4.1 micrometer.
- In terms of shape and size considerable degree of variability can be observed.
- It is a double membrane bound organelle.
- These are present in eukaryotes whereas absent in prokaryotes and in mature RBCs.
- These are also known as 'Plastochondria'/ Chondriosome / Bioplast/ semi autonomous cell organelle or "power house of the cell"
- These were firstly discovered by Richman Altman who called it Bioplast...later which were given the name" Mitochondria " by Carl Benda.
- It divides by fission.
________________________________________
• STRUCTURE :
- It's outer membrane and inner membrane divide it's lumen into two aqueous compartments, i.e. The outer compartment and the inner compartment.
- The inner compartment is called Matrix which is a site for kerb's cycle.
-It's matrix is aqueous, colloidal amorphous structure which carries a single copy of double stranded circular DNA.
-Along with it it's matrix also contains few RNA molecules, ribosomes (70s) and the components required for the synthesis of protein.
- it's outer membrane forms the continuous limiting boundary of the organelle.
- The inner membrane forms a no. Of infoldings called the " cristae " towards the matrix... Cristae increase the surface Area.
- The space between the outer membrane and the inner membrane is called " Perimitochondrial space".
Which is a site of link reaction.
- It's inner membrane is the site of ETS / Oxidative Phosphyrylation.
- Outer membrane have Porins.
- It also possesses Fo - F1 particle /oxysome that involves in oxidative phosphorylation.
