NEET BIOLOGY

Detailed explanation-1: -The light reaction is the initial stage of photosynthesis which traps light energy to produce ATP and NADPH, whereas dark reaction is the second step of photosynthesis which utilizes the energy from ATP and NADPH to produce glucose.

Detailed explanation-2: -The reactants of photosynthesis are carbon dioxide and water. We’ve established that plants need carbon dioxide (CO2) and water (H2O) to produce their food, but where do these reactants come from and how do they get where they need to go inside the plant?

Detailed explanation-3: -The light independent process (also called dark reactions or the Calvin-Benson cycle) takes place in the stroma of the chloroplast. Carbon dioxide is modified by series of chemical reactions to form carbohydrates. The energy for these reactions comes from ATP and NADPH generated during the light dependent process.

Detailed explanation-4: -In light-independent reactions (the Calvin cycle), carbohydrate molecules are assembled from carbon dioxide using the chemical energy harvested during the light-dependent reactions.

Detailed explanation-5: -Explanation: The products of the light independent reaction are glucose, NADP+, and H2O. The reactants are CO2, NADPH, and ATP.
