Detailed explanation-1: -In this reaction, the energy from ATP and NADPH are used to fix carbon dioxide (CO2). So NADH is not a product of the light reaction of photosynthesis.

Detailed explanation-2: -During photosynthesis, light energy converts carbon dioxide and water (the reactants) into glucose and oxygen (the products).

Detailed explanation-3: -The reactants involved in the light reaction are NADP, ADP, and water molecules. After the completion of light reactions, the products obtained are the energy-rich molecules ATP NADPH, and oxygen, the last of which is already considered a by-product of photosynthesis.

Detailed explanation-4: -The synthesis of glucose occurs in stroma and this does not require light. Hence, the reaction for synthesis of glucose is a light-independent reaction.

Detailed explanation-5: -The reactants in the light-dependent chemical reaction are adenosine diphosphate (ADP), oxydized nicotinamide adenine dinucleotide phosphate (NADP+) and the hydrogen in water.
