Photosynthesis Quiz

1. Which of the following occurs in the stroma of the chloroplast?
light dependent reaction
electron transport chain
calvin cycle
photolysis

2. The oxygen produced in photosynthesis comes from what molecule?
glucose
water
P680
ATP

3. The photosynthetic process used by some plants to survive in a hot dry climate, like the desert?
C4 Photosynthesis
C3 Photosynthesis
Noncyclic photophosphorylation
Carbon fixation

4. Which of the following is NOT a produce of the light dependent reaction?
Oxygen
ATP
NADPH
Sugar

5. Which of the following i the source of the carbon in sugar produced during photosynthesis?
carbon dioxide
water
rubisco
ATP

6. Which of the following is the main difference between cyclic and noncyclic photophosphorylation?
they use different electron acceptors
Only photosystem I is used during the cyclic process
noncyclic photophosphorylation occurs in the stroma
noncyclic photophosphorylation does not produce ATP

7. Carbon fixation is catalyzed by what enzyme?
P700
NADPH
phosphoglycerate
rubisco

8. The calvin cycle requires each of the following inputs EXCEPT:
ATP
NADPH
O2
CO2

9. In the light dependent reactions, when light strikes the pigments (P700 or P680) what is the immediate result?
excited electrons are passed to electron acceptors
electrons are fused to form ATP
glucose is produced
carbon fixation occurs

10. In the calvin cycle, more ATP than NADPH is used, how is this difference made up?
the cyclic pathway creates more ATP
the calvin cycle occurs half as often as the light dependent reaction
additional ATP is created from glucose
excess NADPH is reused in the light reaction
