Input (English): Malfunctions of this organelle include Wilson's disease, Kaerns-Sayre syndrome, and Leber's hereditary optic neuropathy. It can be found in long traveling chains, and the malate-aspartate shuttle is used between it and the cytosol. Its namesake uncoupling occurs in brown fat, and apoptosis is induced when cytochrome c is released from it. Its cristae are formed by its inner membrane, which is evidence of its endosymbiotic origin. For 10 points, name this organelle whose matrix is the site of the citric acid cycle, the so-called powerhouse of the cell.
Output (English): Science
