Detailed explanation-1: -The net effect of these steps is to convert light energy into chemical energy in the form of ATP and NADPH. The ATP and NADPH from the light-dependent reactions are used to make sugars in the next stage of photosynthesis, the Calvin cycle.
Detailed explanation-2: -Explain how the light reactions and light independent reactions (Calvin cycle) of photosynthesis are interdependent on each other. The light reactions produces ATP and NADPH, which are then used in the Calvin cycle. The light reactions produce NADP+ and ADP, which are then used in the Calvin cycle.
Detailed explanation-3: -During the light-dependent stage of photosynthesis: Reduced NADP is produced when hydrogen ions combine with the carrier molecule NADP using electrons from the photolysis of water. ATP is produced (from ADP and Pi by ATP synthase in a process called photophosphorylation (ADP + Pi
