light independent reaction Flashcards
(14 cards)
Where does this occur?
In the stroma in the chloroplasts
What does it need?
Reduced NADP and ATP
Where does it get them from?
The light dependent reaction
Where does the carbon dioxide go?
Into the leaf and through the mesophyll cells
It dissolves into the stroma.
What does the carbon dioxide combine with?
RuBP
How many carbons are present in this molecule?
5
What is the process where they combine called?
Fixing
What does this form?
2x GP
How many carbons are present in GP?
3
Which enzyme catalyses this reaction?
Rubisco
What happens to the GP?
They are reduced to form 2x triose phosphate
How are they reduced?
Using reduced NADP and ATP
What are the triose phosphate molecules then used for?
Form all photosynthetic products, regenerate the carbon dioxide acceptor molecule RuBP
Why does temperature affect photosynthesis?
It affects the enzymes used in the light independent reaction
