Episode notes
Complex Cells and Mitochondria
- Mitochondria, found in complex cells like plants and animals, were once bacteria.
- These cells have a nucleus containing DNA and other components, including mitochondria, which act as power packs.
Mitochondria as Batteries
- Mitochondria function as tiny batteries, electrically charged and powering complex life.
- This electrical charge, though seemingly small, equates to a lightning bolt at the molecular level.
ATP: The Universal Energy Currency
- ATP molecules serve as a universal energy currency, converting food and light into usable energy for cells.
- This energy fuels various cellular processes, from muscle contraction to neuron signal transmission.
