Mitochondrial fission is important since it serves various functions such as ensuring proper inheritance during cell division, releasing cytochrome C during programmed cell death, and distributing mitochondria effectively within cells. Additionally, it plays a vital role in eliminating damaged mitochondria through mitophagy. Mitochondrial fusion is also important since it facilitates the exchange of essential gene products between mitochondria, ensuring ideal function particularly during metabolic or environmental stressors.
