**NAME (last name first) \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_** **Study guide -- Chapter 10 - Photosynthesis** 1. Compare main Anabolic and Catabolic pathways Type of Metabolism Anabolic (biosynthetic) Catabolic (breakdown) --------------------------------------------------------- ------------------------- ----------------------- Main pathway Photosynthesis Cellular Respiration Organelle where it takes place Chloroplasts Mitochondria What energy does it use/where does its energy come from Sunlight Glucose Products it generates Glucose and O2 ATP Exergonic or endergonic Exergonic Endergonic 2. Definition of photosynthesis the process that converts solar energy into chemical energy 3. Difference between autotrophs (producers) and heterotrophs (consumers) Autotrophs are photoautorophs that use the sunlight as energy and Heterotrophs depends on photoautorophs 4. About the chloroplast a. Location: Mesophyll b. Structure (make a drawing of the chloroplast and include outer membrane, inner membrane, thylakoids and stroma) 5. **Compare the equation photosynthesis with the equation for cellular respiration by writing both of them in the space below** 6. Name the two stages of photosynthesis and the location in the chloroplast where they take place The Light Reactions (The photo part) Located in the thylakoid and The Calvin Cycle located in the cycle (The Synthesis Part) 7. Which are the main photosynthetic pigments and what color of the spectrum do they absorb light? chlorophyll a and the color of the spectrum they absorb light in is Blue and Red 8. Which are the three products of the light reactions of photosynthesis? O2 and ATP and NADPH 9. What is a photosystem and how many photosystems are present in the thylakoid membranes of the chloroplast? 10. During the Calvin cycle, carbon fixation takes place. What does this mean? Incorporation of C02 into organic molecules 11. What are the products of the Calvin Cycle? **Sugar** 12. **What is the name of the main enzyme of the Calvin cycle in photosynthesis?** **Rubsico** 13. **What is the importance of photosynthesis?** The energy entering chloroplasts as sunlight gets stored as chemical energy in organic compounds Sugar made in the chloroplasts supplies chemical energy and carbon skeletons to synthesize the organic molecules of cells Plants store excess sugar as starch in structures such as roots, tubers, seeds, and fruits In addition to food production, photosynthesis produces the O2 in our atmosphere
