Structure of Mitochondria..

Answer ⤵

The structure comprises an outer membrane, an inner membrane, and a gel-like material called the matrix. The outer membrane and the inner membrane are made of proteins and phospholipid layers separated by the intermembrane space.

$\Large\bold{\underline{\purple{Answer}}}$

$\small\bold\blue{Structure\:of \: Mitochondria}$

• 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 periplastidial space.

• The outer membrane has special proteins known as porins.

• It is freely permeable to nutrient molecules, ions, energy molecules like the ATP and ADP molecules.

• It is 60 to 75 angstroms (Å) thick.

• The inner membrane folds inwards to form finger-like projection known as cristae which help to increase the surface area for absorption.

• It is studed with 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.
