8.3 - Photosynthesis
Assessment statements
DCS Topic Code | Statement | Guidance |
8.3.U1 | Light-dependent reactions take place in the intermembrane space of the thylakoids. | |
8.3.U2 | Light-independent reactions take place in the stroma. | |
8.3.U3 | Reduced NADP and ATP are produced in the light-dependent reactions. | |
8.3.U4 | Absorption of light by photosystems generates excited electrons. | |
8.3.U5 | Photolysis of water generates electrons for use in the light-dependent reactions. | |
8.3.U6 | Transfer of excited electrons occurs between carriers in thylakoid membranes. | |
8.3.U7 | Excited electrons from Photosystem II are used to contribute to generate a proton gradient. | |
8.3.U8 | ATP synthase in thylakoids generates ATP using the proton gradient. | |
8.3.U9 | Excited electrons from Photosystem I are used to reduce NADP. | |
8.3.U10 | In the light-independent reactions a carboxylase catalyses the carboxylation of ribulose bisphosphate. | |
8.3.U11 | Glycerate 3-phosphate is reduced to triose phosphate using reduced NADP and ATP. | |
8.3.U12 | Triose phosphate is used to regenerate RuBP and produce carbohydrates. | |
8.3.U13 | Ribulose bisphosphate is reformed using ATP. | |
8.3.U14 | The structure of the chloroplast is adapted to its function in photosynthesis. | |
8.3.A1 | Calvin’s experiment to elucidate the carboxylation of RuBP. | |
8.3.S1 | Annotation of a diagram to indicate the adaptations of a chloroplast to its function. |
