Light Independent Reaction Flashcards
Where does the light independent reaction take place?
In the stroma of chloroplasts
What molecules from LDR is used for the LIR?
ATP
NADPH
How does the LIR start?
RuBp reacts with CO2 to produce 6 C molecule
RuBp full name
Ribulose bisphosphate
Rubisco
Catalyses reaction of CO2 and RuBP
RuBP + CO2 produces?
2 molecules of GP
What happens to the 2 molecules of GP
It is reduced by gaining electron and H+ from NADPH (with energy released in the form of ATP)
To form 2 molecules of triose phosphate
What happens toNADPH?
It is oxidised back to NADP
2 molecules of triose phosphate can…
Regenerate RuBP (energy released from ATP)
Forms organic substances
How many turns of the cycle are required to produce 1 molecule of glucose?
6 Turns (shown in equation that 6CO2 is used)
6 Turns of the Calvin cycle…
Generates 12 triose phosphate = 36 carbon present
1 glucose molecule (6 carbon) 5 RuBP (30 carbon because one RuBP has 5 carbon)
