Most of the enzymatic reactions of ascorbate biosynthesis occur in the cytosol,with the exception of the terminal step,catalyzed by L-galactono-1,4-lactone dehydrogenase,which is localized on the inner mitochondrial membrane.Given the location of L-galactono-1,4-lactone dehydrogenase,the rate of ascorbate biosynthesis is intimately associated with the rate of mitochondrial respiration (Nunes-Nesi et al.,2005).
