Photosynthesis is the process by which autotrophs fix CO2 into organic compounds. For the process, the light-dependent phase of photosynthesis produces ATP and NADPH which in turn enter into the light-independent phase to fix CO2.
During the light-dependent phase, the splitting of water in the presence of sunlight is followed by the release of electrons from the reaction center of PSII. Passing of electrons through the electron transport chain to the PSI and finally to NADP reductase produces NADPH. The proton concentration gradient is generated across the thylakoid membrane during electron transfer through the electron transport chain. The energy of the gradient is used to drive the ADP phosphorylation into ATP. The whole process is called non-cyclic phosphorylation.
