ViviIn the light reaction, e- are donated by H20 in photosystem II which is located in the thylakoid membrane. In photosystem one, the NADP+ is reduced to NADPH with the electrons from PS II.
Fun fact. Hydrogens from H20 also create a proton gradiant between stroma and thylakoid membrane driving CF1CF0 ATP synthase.

Where electrons get their energy in the light reactions?
.From photons in solar energy
Where do electrons get their energy from light reactions?
From the photons is solar energy.
What is reduced by electrons in light reactions?
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.
What does energy come from to make nadaph in light reactions?
From electrons in photosystem I that are excited to a higher energy state by photons of light. Then NADP + is reduced to become NADPH
What reactions convert light energy to chemical energy?
The light dependent reactions take in the light energy and convert that to chemical energy, but it is in the Calvin cycle (light independent reactions) where the chemical energy is stored in a complex sugar.
