WebSymptoms of mitochondrial diseases can include muscle weakness, lack of coordination, stroke-like episodes, and loss of vision and hearing. Most affected people are diagnosed in childhood, although there are some adult-onset diseases. Identifying and treating mitochondrial disorders is a specialized medical field. WebJun 26, 2002 · describes reactions involved in the disposal of TCA cycle inter-mediates. There are several cataplerotic enzymes; these in-clude PEPCK, aspartate aminotransferase, and glutamate de-hydrogenase. Each of these reactions has as substrate a TCA cycle anion that is converted to a product that effectively re-moves intermediates from the cycle.
