The enzyme, succinate dehydrogenase, catalyzes Step 6 of the Citric Acid Cycle. In this reaction, succinate is converted to fumarate and electrons and protons are transferred to FAD to make FADH2. In this reaction, FAD is the __________ for succinate dehydrogenase, and FAD is the __________ form of the molecule.
