Free inorganic phosphate (pi) is transported in to the mitochondria from the cytosol by a phosphate carrier which is driven by the:
◯ simultaneous transport of H⁺ out of the mitochondrion
◯ simultaneous transport of ADP out of the mitochondrion
◯ hydrolysis of ATP
◯ simultaneous transport of ADP in to the mitochondrion
◯ simultaneous transport of H⁺ in to the mitochondrion
