What happens to most of the triose phosphate molecules (TP) instead?
They are used to regenerate ribulose biphosphate (RuBP) using ATP from the light-dependent reaction
10 of 13
Where does the light-independent reaction take place?
In the chloroplast stroma
11 of 13
Give four reasons as to how the stroma is adapted to the light-independent reaction?
- It contains necessary enzymes - It is membrane bound so it is a fluid highly concentrated with enzymes and substrates can be maintained within it - Surrounds grana so products of light-dependent reaction can easily diffuse into stroma -->

-->
Contains DNA and ribosomes so can quickly synthesise proteins involved in the light-independent reaction
