Photosynthesis Stomata open and close for gas exchange: CO2 and oxygen – carbon dioxide is a reactant of the dark reactions Cellular respiration occurs in D – photosynthesis occurs in chloroplasts In a plant cell where do the light reactions of photosynthesis take place A. Stomata B. Stroma C. Thylakoids D. Mitochondria

Chemical products of the light reactions are oxygen Photosynthesis Chemical products of the light reactions are oxygen A. ADP and NADPH B. Sugar and Water C. Carbon dioxide and ATP D. ATP and NADPH ADP is a chemical product of the Calvin Cycle – ADP is recycled in the light reactions to ATP (NADP+ is recycled to NADPH) CO2 is a reactant of the Calvin cycle Sugar is a product of the Calvin Cycle

The stage of photosynthesis that uses the most ATP is Light reactions Calvin Cycle Electron transport Chain Glycolysis Light reactions PRODUCE ATP Glycolyis is a process during cellular respiration in the mitochondria

Calvin Cycle converts Carbon dioxide to Photosynthesis Calvin Cycle converts Carbon dioxide to ADP and NADPH Water Sugar (gp3) chlorophyll Sugar is glucose (sugar are also carbohydrates) Water is a reactant of the LIGHT reactions Chlorophyll is the molecule that accepts the light rays

Electron Transport Chain Carbon Cycle Electromagnetic spectrum The process by which carbon moves from inorganic carbon dioxide to organic compounds and back is called Electron Transport Chain Carbon Cycle Electromagnetic spectrum Chromotography Carbon cycle cycles carbon from the atomosphere to food: CO2 = gas in the atmosphere It is converted to sugar C6H12O6 C6= 6 carbon molecules Animals eat the plants and exhale the carbon as CO2 Photosynthesis
