The figure below shows the structure of a mitochondrion with its four parts labelled (A), (B), (C) and (D).
Select the part correctly matched with its function:
Part (D): Outer membrane - gives rise to inner membrane by splitting.
Part (B): Inner membrane - forms infoldings called cristae.
Part (C): Cristae - possess single circular DNA molecule and ribosomes.
Part (A): Matrix - major site for respiratory chain enzymes.
As we learnt in
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.
