[单选题]
In which structure of the chloropl8)9rcq5 tntfqast does rd-7b )+m plo3a30wudrkbs.gkibulose bisphosphate undergo carboxylat )dkmbog.r0palbwku 7d-+ s33ion?
A. Thylakoid space
B. Stroma
C. Thylakoid membrane
D. Chloroplast membrane
参考答案: B
本题详细解析:
B The carboxylation of ribulose bisphosphate is the first step in the light-independent reactions (the Calvin cycle) of photosynthesis. During the light-dependent reactions, protons accumulate within the thylakoid space (Choice A) to create the proton gradient that powers the production of NADPH and ATP. The light-dependent reactions of photosynthesis take place on the thylakoid membrane (Choice C). The chloroplast membrane (Choice D) separates the chloroplast from the rest of the cell.
