Detailed explanation-1: -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-2: -Glyceraldehyde 3-phosphate or G3P is the product of the Calvin cycle. It is a 3-carbon sugar that is the starting point for the synthesis of other carbohydrates. Some of this G3P is used to regenerate the RuBP to continue the cycle, but some is available for molecular synthesis and is used to make fructose diphosphate.

Detailed explanation-3: -The product of the Calvin cycle is glyceraldehyde-3 phosphate and RuBisCO is regenerated. The product of the Calvin cycle is a 3-PGA molecule and glyceraldehyde-3 phosphate is regenerated.

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 is the term used for the reactions of photosynthesis that use the energy stored by the light-dependent reactions to form glucose and other carbohydrate molecules.
