They are responsible for producing adenosine triphosphate (ATP), the primary energy carrier, through cellular respiration processes such as oxidative phosphorylation. ATP is vital for fueling many cellular functions, including muscle contraction, protein synthesis, and cell division. Beyond energy production, mitochondria also play a crucial role in regulating cell death, signaling, and maintaining cellular homeostasis. Healthy mitochondria are necessary for overall well-being, as mitochondrial dysfunction is associated with various diseases, including neurodegenerative disorders. Understanding the role of mitochondria in health and their impact on diseases is essential for advancing medical treatments. (1) Proper mitochondrial function ensures optimal metabolic performance and is linked to preventing mitochondrial diseases. Maintaining mitochondrial health is therefore crucial for longevity and preventing degenerative conditions. Recent advances have further clarified how mitochondria influence not only energy metabolism but also various other aspects of cell biology. (2) Additionally, dysfunction in these organelles is now recognized as a significant factor in many genetic disorders. Exploring mitochondrial dynamics offers insights into improving treatments for neurological conditions. To conclude, understanding mitochondrial functions is indispensable for comprehending their role in health and disease.
