Mitochondrial ultrastructure. (A) EM image depicting a mitochondrion (HeLa cell). The white box indicates the magnified view in (C). (B) Schematic representation of mitochondrial ultrastructure showing the mitochondrial matrix enveloped by the MIM and MOM. Between the MIM and MOM lies the IMS. (C) Magnification of the box in (A) to illustrate mitochondrial ultrastructure depicting the IBM, CJ, and CM. (D) Schematic representation of mitochondrial ultrastructure. Structural parameters include the distance between the MIM and MOM (marked “a”) and the intracristae space (marked “b”). (D) was adapted from (404). CJ, cristae junction; CM, cristae membrane; EM, electron microscopy; IBM, inner boundary membrane. Color images are available online.
