A mitochondrial membrane complex consisting of ATP synthase, adenine nucleotide translocase (ATP-ADP translocase), and phosphate translocase functions in oxidative phosphorylation. Adenine nucleotide translocase, an antiporter located in the inner mitochondrial membrane, moves ADP into the matrix and ATP out. Phosphate translocase is also located in the inner mitochondrial membrane. It transports H ions and phosphate (H2PO4–) ions into the matrix. The energy derived from the movement of H ions down an electrochemical gradient from the intermembrane space into the matrix is used to drive the synthesis of ATP. How many H ions must be moved into the matrix for the synthesis of 1 ATP?
