Explain ATP and reduced NADP in the Calvin cycle using evidence from each question and mark scheme.
Photosynthesis is the energy transfer process that occurs in chloroplasts.
Fig. 5.1 shows some biochemical events that occur in a chloroplast during the light-dependent stage of photosynthesis. Photosystems I and II (PSI and PSII) and some associated proteins of the thylakoid membrane are shown.

Product D is used during the Calvin cycle.
Identify product D and describe its specific role in the Calvin cycle.
1 D = reduced NADP ;
2 reduces / gives hydrogen to, glycerate (3) phosphate / GP ;
3 forming, triose phosphate / TP ;
