Light Independent Reaction
ATP & NADPH from light reactions used as energy Atmospheric C02 is used to make intermediate product G3P (glyceraldehyde 3 phosphate) Occurs in the stroma In the cytosol, six-carbon sugars (like glucose and fructose) are made with the product from the Calvin Cycle copyright jemslie

The Calvin Cycle copyright jemslie
6
The Calvin Cycle Two turns of the Calvin Cycle are required to make one molecule of glucose 3 CO2 molecules enter the cycle and bond to 3 molecules of RuBP These immediately split to form six molecules of the intermediate compound (PGA) A 5-carbon molecule called Ribulose Biphosphate (RuBP) is used to regenerate the Calvin cycle copyright jemslie
