The synthesis of ATP from ADP and inorganic phosphate
The reduction of NADP⁺ to NADPH + H⁺
The transfer of electrons from photosystem II to NADP⁺
The transfer of electrons from photosystem II to photosystem I
Solution
The Z scheme refers to the transfer of electrons from photosystem II, uphill to an electron acceptor, down the electron transport chain to photosystem I, excitation of electrons, transfer to another acceptor, and finally down hill to NADP⁺ reducing it to NADPH + H⁺.
