Mitochondria -

Each mitochondria is a double membrane bound structure with the outer membrane and the inner membrane dividing its lumen distinctly into two aqueous compartments.

 

- wherein

It is the site of aerobic respiration. It produces cellular energy in the form of ATP, hence called as 'power house' of the cell.

 

 

Mitochondria are the ATP producing organelles. The electron transport chain is responsible for generation of ATPs through chemiosmosis.The enzymes for the electron transport chain are embedded in inner membrane.
