Mitochondrial Fission

Meaning

Mitochondrial Fission is the dynamic cellular process where a single mitochondrion divides into two or more smaller, separate organelles, playing a critical role in mitochondrial quality control, cellular energy distribution, and programmed cell death. This division is a tightly regulated event, essential for segregating damaged mitochondrial components and ensuring the proper inheritance of mitochondria during cell division. An imbalance between fission and the opposing process, fusion, is often implicated in metabolic dysfunction and age-related decline.
