Explain the light-independent reaction of photosynthesis [8]

The energy in the form of ATP and NADPH made in the light dependent reaction is then used in the light independent reaction to fix carbon from carbon dioxide into organic molecules. This reaction is called the Calvin cycle and it takes place in the stroma of the chloroplast and is controlled by enzymes. Firstly a single carbon in carbon dioxide is fixed with RuBP and is catalyzed by the enzyme Rubisco to form 2 molecules of Glycerate-3-phosphate. The Glycerate-3-phosphate is then reduced to triose phosphate by using the energy which comes from the oxidation of NADPH and ATP. Triose phosphate is then used to regenerate Ribulose Bisphosphate.
