Detailed explanation-1: -The ATP and NADPH from the light-dependent reactions are used to make sugars in the next stage of photosynthesis, the Calvin cycle. In another form of the light reactions, called cyclic photophosphorylation, electrons follow a different, circular path and only ATP (no NADPH) is produced.
Detailed explanation-2: -ATP and NADPH produced by the light-dependent reactions of the photosystems are used by the Calvin cycle in the stroma of the chloroplast.
Detailed explanation-3: -The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH.
Detailed explanation-4: -Explanation: The light dependent reaction converts solar energy to chemical energy, using the photosystem to capture light energy, and ultimately produce ATP and NADPH.
Detailed explanation-5: -How are ATP and NADPH made in the light reactions? Hydrogen ions actively pumped into the thylakoid membrane flow passively through ATP synthase, adding a phosphate to ADP, creating ATP.
