A mitochondrial membrane complex consisting of ATP synthase,adenine nucleotide translocase (ATP-ADP translocase), and phosphatetranslocase functions in oxidative phosphorylation. Adeninenucleotide translocase, an antiporter located in the innermitochondrial membrane, moves ADP into the matrix and ATP out.Phosphate translocase is also located in the inner mitochondrialmembrane. It transports H ions and phosphate (H2PO4–) ions into thematrix.
