front 8 The conversion of light energy into chemical energy occurs in a ________ inside chloroplasts. | back 8 photosystem |
front 9 Which of the following statements best describes the relationship between photosynthesis and respiration? | back 9 Respiration is the reversal of the biochemical pathways of photosynthesis. |
front 10 In any ecosystem, terrestrial or aquatic, what group(s) is (are) always necessary? | back 10 autotrophs |
front 11 CAM plants keep stomata closed in daytime, thus reducing loss of water. They can do this because they | back 11 fix CO2 into organic acids during the night. |

front 13 The sugar that results from three "turns" of the Calvin cycle is glyceraldehyde-3-phosphate (G3P). Which of the following is a consequence of this? | back 13 NOT G3P is easier for a plant to store. |
front 14 Which of the following statements best represents the relationships between the light reactions and the Calvin cycle? | back 14 The light reactions provide ATP and NADPH to the Calvin cycle, and the cycle returns ADP, Pi, and NADP+ to the light reactions. |
front 15 In autotrophic bacteria, where are the enzymes located that can carry on organic synthesis? | back 15 along the inner surface of the plasma membrane |
front 16 Plastids are storage organelles. A chloroplast is a type of plastid. What does a chloroplast store? | back 16 chlorophyll |
front 17 Synthesis of ATP by the chemiosmotic mechanism occurs during | back 17 both photosynthesis and respiration |
front 18 The chemical reactions of photosynthesis occur in which cellular organelle? | back 18 Cholorplasts |
front 19 Some bacteria are photosynthetic. Part of the definition of a prokaryote is that they have no membrane-bound organelles, including chloroplasts. Explain how bacteria carry out photosynthesis without chloroplasts. | back 19 they still have thylakoids, they are just not compartmentalized into chloroplasts |
front 20 Which group includes photosynthetic members? | back 20 bacteria, plants, and protists |
front 21 The light reactions of photosynthesis ultimately convert low-energy molecules of ________ into high-energy molecules of ________. | back 21 NOT NADP+; NADPH and NOT "neither of these are correct" |
front 22 What is the role of light in photosynthesis? | back 22 it energizes electrons |

front 24 Organize the following steps of the light reaction in order. | back 24 NOT Absorb sunlight, produce high-energy electron carriers, split water, produce oxygen |
front 25 Which of the following sequences correctly represents the flow of electrons during photosynthesis? | back 25 H2O → NADPH → Calvin cycle |
front 26 Reduction of NADP+ occurs during | back 26 photosynthesis. |
front 27 What is the role of chloroplasts in animals? | back 27 None, as animals do not have chloroplasts |
front 28 During a process called photoact, ________ give up an electron as a part of the light-dependent reactions. | back 28 chlorophylls |
front 29 Which of the following does not occur during the Calvin cycle? | back 29 release of oxygen |
front 30 What is the primary function of the Calvin cycle? | back 30 synthesize simple sugars from carbon dioxide |
