1 In a plant cell where do the light reactions of photosynthesis take place A. Stomata B. Stroma C. Thylakoids D. Mitochondria 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 Photosynthesis

2 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 Photosynthesis

3 The stage of photosynthesis that uses the most ATP is A.Light reactions B.Calvin Cycle C.Electron transport Chain D.Glycolysis Light reactions PRODUCE ATP Glycolyis is a process during cellular respiration in the mitochondria Photosynthesis

4 Calvin Cycle converts Carbon dioxide to A.ADP and NADPH B.Water C.Sugar (gp3) D.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

5 The process by which carbon moves from inorganic carbon dioxide to organic compounds and back is called A.Electron Transport Chain B.Carbon Cycle C.Electromagnetic spectrum D.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
