Detailed explanation-1: -So, the correct option is ‘Light’.
Detailed explanation-2: -Overall, the reactants of the Calvin cycle are CO2, ATP, and NADPH, and the products are G3P, ADP, and NADP+. The CO2 is used during the first stage as it is fixed to RuBP by RuBisCo. The ATP and NADPH are not used until the second stage (reduction), producing ADP and NADP+.
Detailed explanation-3: -The reactants are CO2, NADPH, and ATP.
Detailed explanation-4: -Plants rely on the photosynthesis process to obtain energy by two steps: (1) to convert carbon dioxide and water into glucose from sunlight in thylakoids; (2) in the Calvin cycle, energy (adenosine triphosphate, ATP) and oxygen (O2) are released when decomposing glucose into pyruvate in stroma [14].
Detailed explanation-5: -The last stage of the cycle is the regeneration stage where RuBP is regenerated so that more carbon dioxide can be fixed in the plants. So the answer is ‘c) Light’.
