Calvin Cycle

Question 1

what is the calvin cycle

Answer 1

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

Question 2

where does calvin cycle happen

Answer 2

in stroma

Question 3

what happens here

Answer 3

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. **

Question 4

what happens in rearranging PGA to make make PGAL

Answer 4

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

PGAL can later be used to make sugar and glucose

Question 5

what happens in recycling

Answer 5

5 remaining PGAL are rearranged to make RuBP using ATP

Question 6

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

Answer 6

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

Question 7

numbers if 3 CO2

Answer 7

3 three RUBP

3CO2

six PGA

Six ATP

then 6 NADPH

then 6 PGAL

5 PGAL then 3 ATP
