Study Notes
Mitochondria: Key Facts
- Primary function of mitochondria is energy production, specifically ATP synthesis through oxidative phosphorylation.
- Mitochondria are often referred to as the "powerhouses of the cell" due to their role in energy metabolism.
- Mitochondria were first discovered by Richard Altmann in the voluntary muscles of insects in the late 19th century.
- In some multicellular organisms, such as the genus Hyphomicrobium, mitochondria have been retained despite a complete loss of their mitochondrial genome.
- Mitochondria typically measure about 0.5 to 10 micrometers in diameter when viewed in cross section.
