Mitochondria
Mitochondria are organelles in most eukaryotic cells responsible for ATP production through oxidative phosphorylation. Mitochondria are unique among cellular organelles in that they have their own DNA, separate from the cell’s nuclear DNA, and can replicate independently within the cell. This feature and their double-membrane structure support the endosymbiotic theory that mitochondria originated from free-living prokaryotes. Beyond energy production, mitochondria play crucial roles in regulating cell metabolism, signaling, differentiation, and death (apoptosis). Proper function and health of mitochondria is vital for overall well-being, as mitochondrial dysfunction is linked to metabolic disorders, neurodegenerative diseases, and aging.
