Browsing: Mitochondria
Mitochondria are organelles known as the powerhouses of the cell because they generate most of the cell’s supply of adenosine triphosphate (ATP), used as a source of chemical energy. They are found in the cells of nearly all eukaryotic organisms, from fungi to plants to animals. Mitochondria are unique among organelles because they have their own independent DNA, which supports the theory that they originated from free-living prokaryotes that entered into a symbiotic relationship with primitive eukaryotic cells. This process is known as endosymbiosis. Mitochondria are involved in several other critical cellular processes, including signaling, cellular differentiation, cell death, as well as the control of the cell cycle and cell growth. Moreover, mitochondria play a crucial role in the regulation of the cell’s metabolic control, and their dysfunction is linked to a range of diseases, particularly those affecting tissues with high energy demands like the heart and brain, as well as aging.
