“…The light-dependent photosynthetic electron transport reactions and the ATP synthase are embedded in the chloroplast thylakoid membrane (Spetea et al, 2008). Their assembly, activity, and repair depend on the transfer of metabolites and cofactors (Spetea et al, 2008). Many biochemical reports pointed to the existence of transport activities across the thylakoid membrane (Vambutas et al, 1994;Pottosin and Scho ¨nknecht, 1996;Hinnah and Wagner, 1998;Ettinger et al, 1999;Shingles et al, 2004).…”
