<prompt> Isocitrate dehydrogenase is linked toNADFADNADPFMN  <response>: There are three isoenzymes of isocitrate dehydrogenase. One, which uses NAD, is found only in mitochondria. The other two use NADP and are found in mitochondria and the cytosol. Respiratory-chain-linked oxidation of isocitrate occurs through the NAD-dependent enzyme.
