chosen.content: Mitochondria are known as "the powerhouse of the cell." Mitochondria are organelles found within almost all eukaryotic cells, which are cells containing a nucleus. They convert nutrients into large quantities of chemical energy in the form of adenosine triphosphate, or ATP. Mitochondria function using two processes known as the Krebs cycle (or tricarboxylic acid [TCA] cycle) and the electron transport chain (ETC), to generate ATP. The energy currency, ATP, can be used in many ways, including fuel for muscle movement and brain function. 
  
  The genetic material in mitochondria, called mitochondrial DNA, is inherited maternally. This means mitochondrial DNA comes from the mother. This maternal transmission has been used to trace ancestors down for many generations and has demonstrated great importance in research on human evolution and migration.
