1) Which of the following are products of the light reactions of photosynthesis that are utilized in the Calvin cycle? a) CO2 and glucose b) H2O and O2 c) ADP, i, and NADP+ d) ATP and NADPH 2) Where does the Calvin cycle take place? a) stroma of the chloroplast b) thylakoid membrane c) interior of the thylakoid (thylakoid space) d) outer membrane of the chloroplast 3) What is the primary function of the Calvin cycle? a) use NADPH to release carbon dioxide b) split water and release oxygen c) transport RuBP out of the chloroplast d) synthesize simple sugars from carbon dioxide 4) In the process of carbon fixation, RuBP attaches a CO2 to produce a six-carbon molecule, which is then split to produce two molecules of 3-phosphoglycerate. After phosphorylation and reduction produces glyceraldehyde 3-phosphate (G3P), what more needs to happen to complete the Calvin cycle? a) addition of a pair of electrons from NADPH b) regeneration of ATP from ADP c) regeneration of RuBP d) regeneration of NADP+ 5) Which of the following sequences correctly represents the flow of electrons during photosynthesis? a) NADPH → O2 → CO2 b) H2O → NADPH → Calvin cycle c) NADPH → chlorophyll → Calvin cycle d) NADPH → electron transport chain → O2 6) Which of the following does NOT occur during the Calvin cycle? a) oxidation of NADPH b) release of oxygen c) regeneration of the CO2 acceptor d) consumption of ATP 7) What compound provides the reducing power for Calvin cycle reactions? a) ATP b) NADH c) NADP+ d) NADPH 8) Example of C3 plants is a) Cactus b) Sugarcane c) Paddy d) Pineapple 9) Krantz anatomy can be found on the following plants, Except a) Cactus b) Sugarcane c) Sorghum d) Maize 10) To produce 1 molecule of glucose, Calvin cycle will need a) 6CO2, 12 ATP, 18 NADPH, cycle take place 6 times  b) 6CO2, 18 ATP, 12 NADPH, cycle take place 6 times c) 3CO2, 9 ATP, 6 NADPH, cycle take place 2 times d) 3CO2, 9 ATP, 6 NADPH, cycle take place 3 times
