Learn Biology: Cells—Mitochondria | The Longevity Revolution

Mahalo biology expert Mary Poffenroth tells you about the mitochondria in our cells. Mitochondria --------------------------------------------------------------------- Mitochondria are the powerhouses of the cell, generating most of the cell's energy supply. Within the cell's mitochondria, the food we eat gets turned into energy that we use. That energy is ATP, or adenosine triphosphate, which transports chemical energy within cells. Mitochondria are found in almost all eukaryotic cells.c Under the Microscope --------------------------------------------------------------------- Mitochondria have an outer membrane and an inner membrane with many inner foldings called crystae. Mitochondria also assist with cell growth, cell cycle and cellular death. They even have their own DNA, which is evolutionary evidence that mitochondria and chloroplast were once prokaryotic organisms in the distant past.c Read more by visiting our page at: http://www.mahalo.com/mitochondria/
