Through photosystem II the excited electrons go down a electron transport chain pumping hydrogen ions into the thylacoid space where these ions fall down through an ATP synthase making ATP. In photosystem I the electron transport chain reduces NADP+ to NADPH, an electron carrier.
These molecules now are used in the Calvin cycle to fix carbon into sugars for the plant.
A simplified explanation.

How do the light reactions and dark reactions work together?
The light reactions provide energy carriers for the dark reactions.
What is the relationship between the light and dark reactions in photosynthesis and how do they work together to convert light energy into chemical energy?
The light reactions and dark reactions in photosynthesis are two stages that work together to convert light energy into chemical energy. In the light reactions, light energy is absorbed by chlorophyll in the chloroplasts, leading to the production of ATP and NADPH. These molecules are then used in the dark reactions, also known as the Calvin cycle, to convert carbon dioxide into glucose. Overall, the light reactions provide the energy needed for the dark reactions to occur and for the conversion of light energy into chemical energy.
What is the relationship between the light and dark reactions in photosynthesis?
The light reactions in photosynthesis capture sunlight to produce energy in the form of ATP and NADPH, which are then used in the dark reactions to convert carbon dioxide into glucose. In other words, the light reactions provide the energy needed for the dark reactions to occur and produce sugar.
How are the dark reactions that occur in plants dependent on the light reactions?
The dark reactions that occur in plants are dependent on the light reactions because the dark reactions need ATP and NADPH. ATP and NADPH are energy molecules that dark reactions need to do their job.
True or false The light reactions of photosynthesis can occur only under light conditions and the dark reactions can occur only during the dark hours?
False. The light reactions of photosynthesis require light to convert solar energy into chemical energy, while the dark reactions (Calvin cycle) do not directly rely on light and can occur in both light and dark conditions. However, the dark reactions are indirectly dependent on the products of the light reactions.

How do light reactions provide energy for dark reactions?
In photosynthesis, the light reactions converts the sunlight int chemical energy (ATP molecules, NADH+H). Dark reactions (light independent reactions) do not use sunlight directly, but use energy stored in ATP and NADH molecules combined with CO2 to produce sugars.
Can light provide activation energy?
Yes. Light can provide activation energy. In fact some chemicals must be stored in the dark to prevent unwanted reactions.
How do the light provide energy for the dark reactions?
