Detailed explanation-1: -The immediate products of one turn of the Calvin cycle are 2 glyceraldehyde-3-phosphate (G3P) molecules, 3 ADP, and 2 NADP+.
Detailed explanation-2: -The reactions of the Calvin cycle add carbon (from carbon dioxide in the atmosphere) to a simple five-carbon molecule called RuBP. 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-3: -Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts). This illustration shows that ATP and NADPH produced in the light reactions are used in the Calvin cycle to make sugar.
Detailed explanation-4: -The Calvin cycle takes place in the stroma and uses the ATP and NADPH from the light-dependent reactions to fix carbon dioxide, producing three-carbon sugars-glyceraldehyde-3-phosphate, or G3P, molecules. The Calvin cycle converts ATP to ADP and Pi, and it converts NADPH to NADP+.
Detailed explanation-5: -Products of Calvin Cycle The products formed after a single turn of the Calvin cycle are 3 ADP, 2 glyceraldehyde-3-phosphate (G3P) molecules, and 2 NADP+.
