Resource summary

Question 1

Question
What is needed in photosynthesis to convert carbon dioxide into organic molecules?
Answer
  • Light and hydrogen from the splitting of water
  • ATP and hydrogen from the splitting of water
  • ATP and oxygen from the splitting of water
  • Light and oxygen from the splitting of water

Question 2

Question
How is the proton gradient generated in chloroplasts during photosynthesis?
Answer
  • Flow of electrons from carrier to carrier in the thylakoid membrane causes pumping of proteins across the thylakoid membrane.
  • Light causes protons to flow through protein channels in the thylakoid membrane
  • Light splits water molecules in the stroma, causing the release of protons
  • Protons are pumped across the thylakoid membrane using energy from ATP

Question 3

Question
The energy lost from electrons during the electron transport chain drives which of the following processes?
Answer
  • regeneration of RuBP
  • carbon fixation
  • chemiosmosis
  • photolysis

Question 4

Question
Which of the following statements describes a relationship between photosystem 2 and photosystem 1?
Answer
  • Photosystem 2 produces ATP and NADPH that are used by photosystem 1
  • Photosystem 1 produces ATP and NADPH that are used by photosystem 2
  • The de-energized electron from photosystem 1 fills the void left by the newly energized electron from photosystem 2
  • The de-energized electron from photosystem 2 fills the void left by the newly energized electron from photosystem 1

Question 5

Question
This is the enzyme that catalyzes the transfer of the electron from the​ ferredoxin (last electron carrier) in the electron transport chain.
Answer
  • ATP synthase
  • NADP reductase
  • RuBP Catalase (rubisco)
  • glycerate-3-phosphate

Question 6

Question
Which of the following identifies the two final products of the light dependent reaction?
Answer
  • cytochrome complex and ferrodoxin
  • plastoquinone and ferrodoxin
  • NADPH and ATP
  • NADP+ and ADP

Question 7

Question
Which of the following is an alternative way to synthesize ATP using energy transferred between photosystems 1 & 2?
Answer
  • photolysis
  • non-cyclic photophosphorylation
  • cyclic photophosphorylation
  • action spectrum

Question 8

Question
Complete the sequence describing the reactions in the Calvin Cycle [blank_start]RuBP[blank_end] binds to a [blank_start]CO2[blank_end] molecule --> An [blank_start]unstable[blank_end] [blank_start]6[blank_end]-C compound breaks down into [blank_start]two glycerate-3-phosphates[blank_end] --> The [blank_start]glycerate-3-phosphates[blank_end] react with [blank_start]ATP & NADPH[blank_end] to form [blank_start]two triose phosphates[blank_end] --> [blank_start]Two triose phosphates[blank_end] go out of the Calvin Cycle and synthesize [blank_start]glucose[blank_end]
Answer
  • CO2
  • H2O
  • O2
  • 6
  • 5
  • ATP & NADPH
  • ATP & NADP+
  • ADP & NADPH
  • ADP & NADP+
  • glucose
  • glycerate-3-phosphates
  • two glycerate-3-phosphates
  • two triose phosphates
  • Two triose phosphates
  • unstable
