light reactions
NADPH is the other molecule produced in the second stage of photosynthesis, known as the light-dependent reactions. Both ATP and NADPH are essential for the production of sugars in the Calvin cycle, which is the third stage of photosynthesis.
These stages are called the light reactions and the dark reactions. The light reactions take place in the presence of of light. The dark reactions do not require direct light, however dark reactions in most plants occur during the day.
The Calvin cycle, which is part of the light-independent reactions of photosynthesis, starts with carbon dioxide from the atmosphere being fixed by the enzyme Rubisco. This fixation process leads to the production of intermediate molecules such as 3-phosphoglycerate and eventually results in the formation of glucose. The cycle also requires energy in the form of ATP and NADPH, which are produced during the light-dependent reactions of photosynthesis.
The process during photosynthesis that involves the addition of hydrogen is the reduction of NADP+ to NADPH. This occurs during the light-dependent reactions, where light energy is used to drive the conversion of NADP+ into NADPH by adding hydrogen ions and electrons from water.
The two stages of photosynthesis are the light dependent and the light independent. During the light reactions, light is converted into energy by a process of transferring electrons to and from a special chemical called NADP. In the light independent stage, called the Calvin Cycle, which uses that energy to change carbon dioxide into sugars for the cell's use.

ATP and NADPH
During photosynthesis, the electron acceptor is typically NADP+ (nicotinamide adenine dinucleotide phosphate). NADP+ accepts electrons and protons to form NADPH, which carries the high-energy electrons produced during the light reactions of photosynthesis to the Calvin cycle for the synthesis of carbohydrates.

ATP and NADPH
The electrons that are passed to NADPH during noncyclic photophosphorylation were obtained from water. The ultimate electron and hydrogen acceptor in the noncyclic pathway is NADPH+.
These stages are called the light reactions and the dark reactions. The light reactions take place in the presence of of light. The dark reactions do not require direct light, however dark reactions in most plants occur during the day.
The Calvin cycle includes three main stages: carbon fixation, reduction, and regeneration of RuBP (ribulose-1,5-biphosphate). During these stages, carbon dioxide is converted into sugars using ATP and NADPH generated from the light reactions of photosynthesis.
