What is needed in photosynthesis to convert carbon dioxide into organic molecules?
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
How is the proton gradient generated in chloroplasts during photosynthesis?
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
The energy lost from electrons during the electron transport chain drives which of the following processes?
regeneration of RuBP
carbon fixation
chemiosmosis
photolysis
Which of the following statements describes a relationship between photosystem 2 and photosystem 1?
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
This is the enzyme that catalyzes the transfer of the electron from the ferredoxin (last electron carrier) in the electron transport chain.
ATP synthase
NADP reductase
RuBP Catalase (rubisco)
glycerate-3-phosphate
Which of the following identifies the two final products of the light dependent reaction?
cytochrome complex and ferrodoxin
plastoquinone and ferrodoxin
NADPH and ATP
NADP+ and ADP
Which of the following is an alternative way to synthesize ATP using energy transferred between photosystems 1 & 2?
non-cyclic photophosphorylation
cyclic photophosphorylation
action spectrum
