- Mitochondria are responsible for creating more than 90 percent of the energy needed by the body to sustain life and support growth. ATP energy is produced when the mitochondria transfers glucose and oxygen into water and carbon dioxide. How ATP is produced and delivered to intricate neuronal dendrites has been a mystery.

Scientists in Japan have have discovered how nerve cells adjust to low energy environments during the brain’s growth process. Their study may one day help find treatments for nerve cell damage and neurodegenerative disorders such as Alzheimer’s and Parkinson’s diseases.

Mitochondria, the proverbial “powerhouse” of the cell, mitochondria is found in virtually all eukaryotic cells, plant, or animal. Scientists thought that was pretty much the end of the story of our little friend. It was not a great explanation, but it was an explanation. Now new research is turning the idea– that our ancestor cells simply “swallowed up” bacterial cells that eventually became mitochondria– on its head.
