The adenosine triphosphate (ATP) molecule is produce by energized electrons in the cell respiration and FAD, a process that downgrades the energy level of those electrons, receives these electrons inside the mitochondrion. These ATP synthesized in the mitochondria will be used for cellular processes in the cytosol. Therefore, it must be transferred from its site of synthesis in the mitochondrial matrix. The ADP/ATP translocase is an antiporter used to exchange newly synthesized ATP in the matrix for ADP in the intermembrane space.
