Light Independant Reaction

Question 1

Where does the LIR occur?

Answer 1

In the stroma

Question 2

Stage 1- carbon fixation/carboxylation

Answer 2

RuBP (5 carbon) and CO2 (1 carbon) join, creating a 6 carbon molecule, catalysed by the reaction Rubisco

Question 3

stage 2

Answer 3

then the 6 carbon molecule forms 2 GP molecules (3 carbons each)

Question 4

stage 3

Answer 4

the 2 GP are reduced into 2 TP, using ATP for the energy and NADPH to provide hydrogen

Question 5

stage 4

Answer 5

some TP (1/6) is used to make glucose but cycle needs to happen 6x for 1 molecule of glucose to be made.
the rest of the TP (5/6) are used to regenerate RuBP
