Answer: Photosystem I
Which pigment complex absorbs 680 nm light to energise electrons to power the ETC?
Answer: Photosystem II
What is the final electron acceptor in light reactions?
Answer: NADP⁺
What carries electrons and hydrogen to the stroma for the Calvin cycle?
Answer: NADPH (reduced NADP)
What process makes ATP using light energy in photosynthesis?
Answer: photophosphorylation
Cycle of light-independent reactions in the stroma that fixes CO₂ and regenerates RuBP?
Answer: Calvin cycle
What is the incorporation of CO₂ into organic molecules by RuBisCO?
Answer: Carbon fixation
Which enzyme catalyzes carbon fixation in the Calvin cycle?
Answer: RuBisCO
Which five-carbon molecule accepts CO₂ in the Calvin cycle?
Answer: RuBP
First stable three-carbon compound formed after carbon fixation?
Answer: Glycerate 3-phosphate (GP)
What is the result of the reduction of GP?
Answer: Triose phosphate
Where specifically do the light-independent reactions occur?
Answer: Stroma of the chloroplast
Which two products of the light-dependent reactions are used in the Calvin cycle?
Answer: ATP and reduced NADP
What happens to most (5/6) of the triose phosphate produced?
Answer: Regenerated into RuBP
What molecule provides the energy to regenerate RuBP from TP?
Answer: ATP
Play it as a class game
Play this set opens it in splycr, where you can host it for your class straight away. Hosting needs no account: put the room code on the projector, and students join from a phone with the code and their first name. Each question plays as multiple choice, and the three wrong options are other answers from the same set.
