11.3 The light independent reaction Flashcards
1
Q
what is catalysed by rubisco?
A
the reaction between 5C ribulose bisphosphate (RuBP) and 1C CO2
2
Q
what is the enzyme involved in LIR?
A
rubisco
3
Q
what does rubisco catalyse the production of?
A
an unstable 6C molecule
4
Q
what does the 6C unstable molecule split into?
A
2x Glycerate 3 phosphate
(GP)
5
Q
what does GP get modified into?
A
2x Triose phosphate
(TP)
6
Q
what do you need to turn GP into TP?
A
H+ from NADPH
energy + P from ATP
7
Q
what does TP turn into using ATP
A
back into ribulose bisphosphate
8
Q
how many Cs are lost each cycle?
A
1
9
Q
what is the lost C used for?
A
making organic substances
eg/ glucose and a/a
10
Q
how many cycles do you need for 1 glucose molecule?
A
6
11
Q
where does NADPH and ATP go to after being used?
A
back to the thylakoid
