    Mitochondrial shuttle

    The mitochondrial shuttles are systems used to transport reducing agents across the inner mitochondrial membrane. NADH cannot cross the membrane, but it can reduce another molecule which can cross the membrane, so that its electrons can reach the electron transport chain....

    Translocase of the inner membrane

    The translocase of the inner membrane is a complex of proteins found in the inner mitochondrial membrane of the mitochondria. Components of the TIM complex facilitate the translocation of proteins across the inner membrane and into the matrix ....
