Mitochondria are the energy centers of the eukaryotic cells. In these organelles, ATP (the energy coin of the cell) is produced by the oxidation of pyruvate (Krebs cycle) and oxidative phosphorylation.
- Based on this information, malfunction in MITOCHONDRIA is most likely responsible for Leigh's disease.
- Cellular respiration is series of metabolic reactions by which eukaryotic cells produce energy in the form of ATP from foods and oxygen.
