1. 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

2. 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

3. 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

4. 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

5. 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
