SECRET SUMMARY FINAL PHOTOSYNTHESIS ↳ Carbon Moxide+ water + light energy-GSP (glucose precursor) + oxygen (gain elections) · carbon dioxide is reduced to G3P · CO2 most of plants makes up dry weight · water is oxidized closes electrons) to oxygen ↳2 stages required) · Light dependent reactions (Light is · Produces ATP and NADPH · Calvin cycle (Light is required) Uses ATP and NADPH from light dependent reactions to make G3P CELLULAR RESPIRATION US PHOTOSYNTHESIS ↳ similarities · use electron carriers to move electrons · ETC embedded in anInner membrane and He gradient drives ATP synthesis ↳ Differences · photosynthesis happens in Chloroplast · Chloroplast contain photosynthetic pigments (chlorophil that capture light energy from the Sun - purple wavelengths of light is absorbed the most - Chlorophil provide plant its green color - No Chloropl--white color (no Photosynthesis) LIGHT DEPENDENT REACTIONS ↳ Inputs · ADD + Pi , NADD +, H2O ↳ outputs · ATP , NADPH , Or ↳ I scheme 1. Photosystem 11 (psll) · water is split into OL and supplies electrons to PSI · Light energy excites electrons to a higher energy level. ETC (PS1l 2 to PSD) · electron from PSII travels to an ETC similar to that in cellular respiration ·. He proton pump gradient (Chemiomosis (ATP Synthase 'Photophosphorylation of ATP. Photosystem 3 1 (PSD · Receives electron from first ETC · Light energy excites electrons to a higher energy level 4. ETC (PS1 to NADPH) · Electron from PSI travels down a shortEtC and reduces NADP to NADPH CALVIN CYCLE ↳ Inputs · ATP , NADPH , CO2 ↳ outputs · ADD , NADP +, G34 ↳ steps 1 Carbon Fixation : RrBP CO2 Is fixed. I s the molecule to which by Rubisco 2 Reduction : ATP and NADPH from GBP. light dependent reactions are used to make. 3 Regeneration : RuBp the molecule that starts the CycleI s regenerated so that the cycle can continue
