Class 11 Biology Cell : The Unit of Life Mitochondria

Mitochondria

  • Mitochondrion is a double membrane-bound structure with the outer membrane and the inner membrane dividing its lumen distinctly into the outer compartment and the inner compartment.
  • The inner compartment is called the
  • The outer membrane forms the continuous limiting boundary of the organelle and the inner membrane forms a number of infoldings called the cristae towards the matrix.
  • Mitochondria are the sites of aerobic respiration and produce cellular energy in the form of ATP, hence they are called ‘power houses’ of the cell.
  • The matrix also possesses single circular DNA molecule, a few RNA molecules, ribosomes, and a few components of protein synthesis.
