(a)[4]
Outline the main features of non-cyclic photophosphorylation, which takes place in the light-dependent stage of photosynthesis.
(b)[2]
Some Calvin cycle intermediates are diverted to make other molecules that are not part of the Calvin cycle. Name two of these intermediates. For each one, state one example of the kind of molecule produced.

Calculate the mean rise in the rate at which carbon dioxide is taken up as the temperature increases from $5\,^{\circ}\text{C}$ to $20\,^{\circ}\text{C}$. Show your working. Give your answer to two decimal places.
(c(ii))[3]
Suggest why the rate of carbon dioxide uptake levels off and then falls after $20\,^{\circ}\text{C}$.
(c(iii))[1]
On Fig. 8.1, draw a curve to illustrate the uptake of carbon dioxide on a cloudy day.
