[单选题]
In which structure of the chloroyyo)jhf k1t.67pf2c7 4 a ayhcplast does ribulvw,vhx-eb lk;f )97mk ose bisphosphate undergo carboxylatixwv9kbfk l-h7e;m ) v,on?
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.
