Photophosphorylation in vivo

摘要: As shown in the preceding chapters of this volume, process photophosphorylation (PP) is defined as light-induced synthesis ATP from ADP and inorganic phosphate (Pi): $${\rm{ADP + }}{{\rm{P}}_{\rm{i}}}\mathop \to \limits^{hv} {\rm{ATP}}{\rm{.}}$$ (1) PP confined to thylakoid systems green plants its driving force a proton gradient, which created by photosynthetic electron transport (ET) across membranes. The operation PP can be experimentally demonstrated both intact cells (in vivo) or fragments isolated vitro). Most our present knowledge about mechanism coupling ET arises vitro studies with membranes (cf. volume). Such preparations are for many reasons superior corresponding vivo systems, if basic principles properties investigated (Table 1).
