Botany - Photosynthesis in Higher Plants Question with Solution | TestHub

Non-cyclic photophosphorylation is not only connected with ATP synthesis but also the production of NADPH. It involves two photosystems - PSI and PSII. PSII (680) receive electrons from photolysis of water and transfer it to PSI (700) to form NADPH from NADP⁺. The hydrogen required for reduction comes from the breaking of water molecules.
