摘要

The functional integrity of mitochondria is strictly dependent on the molecular dynamics governing their shape, size, and structure. A sequence of fusion and fission events serve to tailor the mitochondrial reticulum and preserve its morphological and functional homeostasis.The mitochondrial ultrastructure, defined by the alignment and density of cristae, plays a central role in mitochondrial function, dictating both the efficiency of oxidative phosphorylation, through production of adenosine 5-triphosphate (ATP), and the execution of programmed cell death (or apoptosis) by tuning the release of pro-apoptotic molecules stored within the intermembrane space, such as cytochrome c (Cyt c).
