Detailed explanation-1: -These reactions use chemical energy from NADPH and ATP that were produced in the light reactions. The final product of the Calvin cycle is glucose.
Detailed explanation-2: -The Calvin cycle is a progression of reactions that happens in the stoma of chloroplasts in a plant cell. The chemical reactions convert carbon dioxide into glucose with the assistance of ATP and NADPH.
Detailed explanation-3: -So the correct answer is ‘3-PGA’.
Detailed explanation-4: -The immediate products of one turn of the Calvin cycle are 2 glyceraldehyde-3-phosphate (G3P) molecules, 3 ADP, and 2 NADP+. (ADP and NADP+ are not really “products". They are regenerated and later used again in the light-dependent reactions).
Detailed explanation-5: -The Calvin cycle uses carbon from the carbon dioxide, energy from the ATP, and high-energy electrons and hydrogen ions from the NADPH. The cycle’s output is an energy-rich sugar molecule.
