Photosynthesis Flashcards
Which of the following occurs in the stroma of the chloroplast?
- light dependent reaction
- electron transport chain
- calvin cycle
- photolysis
Calvin cycle
The oxygen produced in photosynthesis comes from what molecule?
- glucose
- water
- P680
- ATP
Water
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
C4 Photosynthesis
Which of the following is NOT a produce of the light dependent reaction?
- Oxygen
- ATP
- NADPH
- Sugar
Sugar
Which of the following i the source of the carbon in sugar produced during photosynthesis?
- carbon dioxide
- water
- rubisco
- ATP
Carbon dioxide
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
Only photo system I is used during the noncylic process
Carbon fixation is catalyzed by what enzyme?
- P700
- NADPH
- Phosphoglycerate
- Rubisco
Rubisco
The calvin cycle requires each of the following inputs EXCEPT:
- ATP
- NADPH
- O2
- CO2
O2
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
Excited electrons are passed to electron acceptors
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
The cyclic pathway creates more ATP
