【評論內容】Succinyl-CoA synthetase (SCS) catalyzes succinyl-CoA to produce succinate and GTP/ATP. In mammals, SCS is a heterodimer and is located within the mitochondria. Two different isoforms exist: one is ATP-specific (ATPSCS; EC 6.2.1.5) and the other is GTP-specific (GTPSCS; EC 6.2.1.4). Thus, A and C are correct.Reference: Lehninger Principles of Biochemistry 8/e, David L. Nelson; Michael M. Cox; Aaron A.Hoskins, W. H.
