1

what is the calvin cycle 

a process that happens in stroma, independent from light, and uses CO2  from atmosphere and incoporates it to make PGAL

2

where does calvin cycle happen

in stroma 

3

what happens here 

CO2 is incorporated in one RuBP 5 C chain. 

 

forms a 6 carbon chain, unstable, so splits to 2  kf PGA molecules, each with 3C. 

4

what happens in rearranging PGA to make make PGAL

2 ATP and 2 NADPH are used to rearrang PGA to make PGAL 

 

PGAL can later be used to make sugar and glucose 

5

what happens in recycling 

5 remaining PGAL are rearranged to make RuBP using ATP

6

how many ATP and NADPH are used in one cycle and total molecules number in 1 

6 ATP in rearranging

 

6 NADPH in rearranging 

 

3 more ATP in recycling 

 

mff

 

1 CO2 

 1 RUBP 

2 PGA 

 

2 ATP 

2 ADP=2P 

 

2 NADPh

2 NADPh

 

2 PGAL

1 carbon

 

1 PGAL and 2 carbons 

 

1 ATP and 1 ADP

 

then 1 RUBP 

 

 

7

numbers if 3 CO2

3 three RUBP

3CO2

 

six PGA 

 

Six ATP 

 

then 6 NADPH

 

then 6 PGAL 

 

5 PGAL then 3 ATP
