Calvin Cycle

Question 1

What stage does the Calvin cycle (carbon fixation) happen in?

Answer 1

Light independent stage

Question 2

Where does carbon fixation occur and what does it produce?

Answer 2

Occurs in stroma and produces glucose

Question 3

What is RUBISCO?

Answer 3

Enzyme involved in the process of adding CO2 to 5 carbon compound RuBP

Question 4

How does CO2 enter a plant?

Answer 4

It enters the leaf through the stomata and diffuses into stroma of chloroplast

Question 5

What’s required for the reduction of 3C GP molecules to GALP?

Answer 5

1)Hydrolysis of ATP to provide energy
2)H+ ions which come from reduced NADP

Question 6

What can GALP go on to form?

Answer 6

1)Carbohydrate (glucose)
2)Regenerate RuBP

Question 7

How many molecules of GALP to make glucose?

Answer 7

2

Question 8

How many molecules to regenerate RuBP?

Answer 8

5 out of every 6 molecules of GALP

Question 9

What 2 things require ATP in Calvin Cycle?

Answer 9

-Formation of GALP from GP
-Regenerating of RuBP from GALP
