.From photons in solar energy
From the photons is solar energy.
In light reactions of photosynthesis, electrons are reduced by the pigment molecule chlorophyll to produce NADPH and ATP. These reduced molecules carry energy and electrons to the Calvin cycle for the synthesis of carbohydrates.
Photosynthesis can be broken down into two main stages: light-dependent reactions and light-independent reactions (Calvin cycle). In the light-dependent reactions, light energy is used to split water molecules into oxygen, protons, and electrons. In the Calvin cycle, these electrons are used to assimilate carbon dioxide into organic molecules like glucose.
Water participates directly in the light reactions of photosynthesis by donating electrons to photosystem II during the process of photolysis. These electrons are used to replace the ones lost by chlorophyll when it absorbs light energy, allowing the photosystem to continue absorbing light and generating ATP and NADPH for the Calvin cycle.

ATP is produced from the light reactions, which is then coupled with the light independent reactions. NADPH is also produced, but its job is to carry electrons which eventually make ATP.
Donating electrons to photosystem 2
The light reactions occur in the thylakoid membrane of the chloroplast. The primary goal of the light reactions is to convert light energy into chemical energy in the form of ATP and NADPH. Water is split during the light reactions to provide electrons for the photosystems. The light reactions produce oxygen as a byproduct.

during the light reactions of photosynthesis
Dark reactions can continue to run in the absence of light since they are not dependent on light energy for their process. These reactions, such as the Calvin cycle, use the products of the light-dependent reactions to convert carbon dioxide into sugar molecules. Therefore, they can occur in the dark as long as the necessary molecules and enzymes are present.
