Q: Posttranscriptional insertions and deletions of uridine residues occur in these structures in trypanosomes. These structures are adversely affected in Barth syndrome due to a defect in the biosynthesis of cardiolipin. Other diseases associated with them include Friedreich's ataxia and Kearns-Sayre syndrome. Damage to them results in the formation of a permeability transition pore and can trigger (*) apoptosis through the release of cytochrome c. They may contain thermogenin when found in brown fat, and they contain the malate shuttle, which regenerates NADH inside them. FTP name these organelles that contain F0F1 ATP synthase and that are the sites of the citric acid cycle and the electron transport chain, generating energy for the cell.
