ATP isn't created during the process of photosynthesis. Photosynthesis merely creates glucose, which is afterwards consumed to create the ATP. This ATP, however, serves the purpose all ATP does in the body: energy that the cell can use.
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.
Photosynthesis generates ATP during the light-dependent reactions (photophosphorylation) and NADPH during the light-dependent reactions (photolysis of water and reduction of NADP+ to NADPH).
Yes, they carry energy between the light reactions and the Calvin cycle. ADP is phosphorylated into ATP at the ATP synthase while NADP is reduced by the electrons in the transport chain (it then becomes NADPH).
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.
They are ATP and NADH. They are energy carrying molecules.
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.

NADPH and ATP are produced by the light reactions. The ATP is a high energy molecule produced by photophosphorylation while the NADPH is produced at the end of the electron transport chain.

ATP and NADPH
NADPH is produced during the light reactions of photosynthesis in the thylakoid membrane of chloroplasts. These reactions involve the absorption of light energy, which is used to drive the electron transport chain and ultimately reduce NADP+ to NADPH. The Calvin cycle, which takes place in the stroma of the chloroplast, utilizes NADPH produced in the light reactions to reduce carbon dioxide to carbohydrates.
An easily understood explanation is: NADPH carries high-energy electrons that were produced by light absorption in chlorophyll to chemical reactions elsewhere in the cell. NADPH is a chemical compound which gives hydrogen atom for the formation of the carbohydrate in the dark reactions of the photosynthesis. Photosynthesis is completed in two steps: Light reactions dark reactions Another explanation: NADPH provides a source of hydrogen for reduction reactions in photosynthesis. In the light independent reactions carbon dioxide is converted into carbohydrate: CO2 --------> CH2O NADPH provides the hydrogen needed for this reaction.

Photosynthesis generates ATP during the light-dependent reactions (photophosphorylation) and NADPH during the light-dependent reactions (photolysis of water and reduction of NADP+ to NADPH).
The energy sources for the Calvin cycle are ATP and NADPH, which are produced during the light-dependent reactions of photosynthesis. These molecules provide the necessary energy and reducing power for the conversion of carbon dioxide into carbohydrates in the Calvin cycle.
