describe the ultrastructure of Mitochondria with the help of suitable diagram

Ultrastructure of mitochondria-
  1. Mitochondria are double membrane bound cell organelles. Outer membrane is smooth and tightly stretched, while inner membrane gives rise to finger-like projections into the colourless matrix.
  2. Each crista bears numerous stalked particles or oxysomes. Electron carriers of ETS and enzymes required for ATP synthesis are located on the body of oxysomes. Thus, oxidative phosphorylation i.e. synthesis of ATP during respiration takes place on oxysomes.
  3. Mitochondrial matrix contains enzymes and co-enzymes required for Kareb's cycle.
