This video presents the 2 phases of photosynthesis: the photochemical phase which uses light to oxidize water (H2O) into dioxygen (O2) to produce the intermediate compounds: ATP and NADPH,H+ (RH2). the non-photochemical (or thermochemical) phase which uses the intermediate compounds (ATP and RH2) to reduce CO2 into glucose (C6H12O6). 00:00 Introduction and presentation of photosynthesis 00:36 Diagram of the cell and the chloroplast 00:55 Chloroplast and granary and intergranary thylakoids 01:20 Compartments: cytoplasm, stroma and lumen 01:45 Light capture thanks to photosystems and pigments 02:00 Photolysis of water: H2O is transformed into O2 02:27 Release of H+ ions and electrons 02:45 The photosynthetic chain 03:21 Photosystem and electron acceptor (NADP+ / R) 04:39 ATP synthase and the production of ATP 05:16 Summary Photochemical phase 05:37 Non-photochemical phase (thermochemical) 06:49 Use of ATP and NADPH,H+ (reducing power) 07:21 RuMP and regeneration of RuBP 07:39 Calvin Benson cycle and production of glucose 08:12 Transformation of glucose into starch or sucrose 08:34 Balanced equation of photosynthesis 09:19 Redox reactions of photosynthesis 10:01 End Recommended level: Term SPE SVT, BCPST, L3 Biology Source: http://m.pourcher.free.fr
