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: -Products of Calvin Cycle Generally, the carbohydrate products of the Calvin cycle are the three carbon sugar phosphate molecules or the triose phosphates (G3P). The products formed after a single turn of the Calvin cycle are 3 ADP, 2 glyceraldehyde-3-phosphate (G3P) molecules, and 2 NADP+.
Detailed explanation-3: -After the energy of light is harvested as high-energy electrons held by NADPH, these electrons are then used to synthesize high-energy sugar molecules from the low-energy starting material of carbon dioxide. The Calvin-Benson Cycle used to be called “the dark reactions” because light is not directly involved.
Detailed explanation-4: -The calvin cycle uses six molecules of carbon dioxide, 18 molecules of ATP, and 12 molecules of NADPH to produce one molecule of glucose.
Detailed explanation-5: -The Calvin cycle inevitably produces sugar-derived reactive carbonyl methylglyoxal during photosynthesis: a potential cause of plant diabetes. Plant Cell Physiol.
