## Unit 2 Exam Study Guide 1. What is the source of carbon atoms used to make glucose in Dark Reactions? * CO2 (carbon dioxide) 2. What is the role of water (H2O) in the Light Reactions? * Donates an electron to replace the one lost from the special pair of chlorophylls in PSII. 3. Sunlight energy is classified as what type of energy? * Kinetic 4. Rubisco "fixes" carbon by adding carbon from CO2 into which molecule? * RuBP 5. You place a plant in the dark for a few days. Which of the following will most likely be a result within the chloroplasts? * Lower concentration of H+ in stroma 6. Our bodies store energy in the form of glycogen in our muscles and liver. Glycogen is built by bonding glucose molecules together. A chemical reaction that builds larger molecules from smaller molecules is called... * Anabolic 7. Which type of transport best describes the movement of H+ through the enzyme ATP synthase, which is embedded in the inner mitochondrial membrane? * Passive transport 8. In the conversion of citrate to succinate in the CAC, which molecule is reduced? * NAD+ 9. Some organisms can live in environments with little to no oxygen. How do they make ATP? * Glycolysis 10. Chemical reactions make and or break bonds between atoms and molecules. If the chemical reaction requires energy to convert reactants into products, this reaction is said to be... * Endergonic 11. NAD+ contains a nitrogenous base in its structure. Which nitrogenous base does it contain? * Adenine 12. How many G3Ps are needed to produce 3 RuBPs in the Regeneration step of the Calvin Cycle? * Five 13. Which 4-carbon molecule must be regenerated to continue the CAC? * Oxaloacetate 14. During oxidative phosphorylation, electrons are passed down the electron transport chain. What is the final acceptor of these electrons? * Oxygen 15. In which step in the Calvin Cycle is NADPH oxidized? * Reduction 16. In hot/dry climates, some plants limit their water loss by closing stomata during the day. What type of plant does this? * CAM 17. Oxygen can build up in plant cells when stomata are closed. What effect does this have on the plant? * Less glucose is made 18. Vitamin B-12 is an important cofactor for some enzymes. If a person is deficient in
