Chapter 10 little bit of 9 1. Plants that fix CO2 into organic acids at night when the stoma are open and carry out the Calvin Cycle during the day when the stoma are closed are called CAM Plants 2. Photorespiration lowers the efficiency of the photosynthesis by removing which of the following from the Calvin Cycle? Ribulose biphosphate molecules 3. Figure 10.1 shows the absorption spectrum for chlorophyll a and the action spectrum for the photosynthesis. Why are they different? Other pigments absorb light in addition to chlorophyll a 4. If figure 10.1 showed the absorbance of the total photosynthetic pigments extracted from the plant (instead of pure chlorophyll a), the absorption spectrum curve would Better match the action spectrum 5. Which of the following statements about the light reactions of photosynthesis is FALSE? The proton gradient is used to reduce NADP 6. Which of the following are products of the Calvin Cycle and are utilized in the light reactions of photosynthesis? ADP, Pi, and NADO+ 7. From the photosynthetic action spectrum in Figure 10,2, we can correctly conclude that Plants can use all colors of visible light for photosynthesis 8. The primary function of the light reactions of photosynthesis is

To produce ATP and NADPH 9. The reactions of the Calvin cycle require all of the following molecules EXCEPT Glucose 10. You have just discovered a new flower species that has a unique photosynthetic pigment. The leaves of this plant appear to be reddish yellow. What wavelengths of visible light this pigment is NOT Absorbing Red and yellow 11. All of the events listed below occur in the energy- capturing light reactions of photosynthesis EXCEPT Carbon dioxide is incorporated into PGA 12. Which of the following statements regarding events in the function of photosystems II is FALSE? The P680 chlorophyll donates a pair of protons to NADPH, which is thus converted to NADP+ 13. All of the following compounds are required at some stage of photosynthesis in plants, EXCEPT Oxygen 14. On which of the following features do most plant and animal cells differ? Primary energy source 15. Where does the Calvin cycle take place? Thylakoid membrane

16. CAM plants can keep stomates closed in daytime, thus reducing loss of water. They can do this because they can Fix CO2 into organic acids during the night 17. All of the following statements are correct regarding the Calvin cycle of photosynthesis EXCEPT These reactions begin soon after the sundown and end before sunrise 18. Of the following, the color of light least effective in driving photosynthesis Green 19. Cyclic electron flow in the chloroplast produces ATP 20. In plant cells, ATP is made in response to light. An e- transport chain is involved. This e- transport chain is found in the
