Detailed explanation-1: -ATP and NADPH produced by the light-dependent reactions of the photosystems are used by the Calvin cycle in the stroma of the chloroplast. Molecules of CO2 gas are fixed into molecules of 3-phosphoglycerate in a reaction catalyzed by the enzyme Rubisco.
Detailed explanation-2: -The light-dependent reactions convert light energy into chemical energy. The goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to produce ATP and NADPH. These two energy-storing molecules are then used in the light-independent reactions.
Detailed explanation-3: -The light-independent reactions can proceed once products (NADPH and ATP) of the light-dependent reactions are present in the chloroplast.
Detailed explanation-4: -Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH. The Calvin cycle, which takes place in the stroma, uses energy derived from these compounds to make GA3P from CO2.
Detailed explanation-5: -What the products of the light independent reactions? Explanation: The products of the light independent reaction are glucose, NADP+, and H2O. The reactants are CO2, NADPH, and ATP.
