CAIE A Level Biology 9700 · Photosynthesis
A researcher is investigating the light-dependent reactions of photosynthesis in isolated chloroplasts. As part of the investigation, the researcher compares cyclic and non-cyclic photophosphorylation.
Outline four differences between cyclic and non-cyclic photophosphorylation. Present your answer in a table with two columns: 'Cyclic photophosphorylation' and 'Non-cyclic photophosphorylation'.
4 marks, so the mark scheme is looking for about 4 separate creditworthy points. Making the same point twice in different words earns it once.
Outline means: Give the main points briefly. Less detail than describe, but every key step has to be there. One short line per step, in order. The marks are for coverage, not depth.
