Summary of Mitochondria-
Mitochondria has a double wall membranous structure. The membranes are composed of phospholipids and protein.
The space between the outer and inner membrane is known as perimitochondrial or intermembrane space.
The outer membrane has special proteins known as porins.
The inner membrane folds inwards to form finger-like projection known as cristae which help to increase the surface area for absorption.
It is composed with F0-F1 particles or oxysomes which help in oxidative phosphorylation.
The two membranes enclose a fluid which is known as matrix. It is a complex mixture of proteins and enzymes.
These enzymes are important for the synthesis of ATP molecules, mitochondrial ribosomes, tRNAs and mitochondrial DNA.
It has its own DNA which is mainly used for genetic modification.
