Calvin CycleCurrent LecturePhotosynthesis Part 2Dark reactions (Biochemistry) Often Called: Photosynthetic Carbon Reduction Cycle ORCalvin Cycle Basic idea: ATP and NADPH cause the synthesis of a 3 carbon sugar in the stroma. Explanation of the scientific process that lead to this being discovered These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Basically after World War II there was an excess of radioactive CO2. This was then used totrack the process of carbon dioxide within the cell of algae. Two dimensional paper chromatography was used to separate the products. Biochemistry:-occurs in the stroma-uses ATP+ NADPH + CO2 =>sugar + NADPH+ + ADP+ PCalvin Cycle: Step 1) Caboxylation: a carboxyl group (from CO2) attaches to RuBP (ribulose 1,5 phosphate) -rubisco catalyzes the reaction and produces 3-phosphoglycerate Step 2) Reduction: 3 PGA plus one phosphate from ATP -1,3 biphosphoglycerate and ADP -1,3 BPG + NADPH =>triosphosphate + NADP+ + P Step 3) Regeneration: some of the triose phosphate into
