Quiz 7

Question 1

Where does the Light Independent Rxn occur?

Answer 1

The Stroma

Question 2

What is another word for LIR?

Answer 2

Calvin Cycle

Question 3

What is the equation for LIR?

Answer 3

6CO2 + 12NADPH + 18ATP -> C6H12O6

Question 4

What is carbon fixation?

Answer 4

Converting inorganic carbon (CO2) to organic carbon.

Question 5

Every turn of a Calvin Cycle fixes how many carbon atoms?

Answer 5

1 Carbon atom

Question 6

What is used to start the Calvin Cycle?

Answer 6

6CO2 and 6 Ribulose bisphosphate (RuBP, 5C-2P).

Question 7

What two things occur during the Calvin Cycle?

Answer 7

Reduction and Regeneration

Question 8

What happens in Reduction?

Answer 8

Gaining e- and more energy. 12ATP -> 12 ADP+Pi

Question 9

How many electrons are used in Reduction?

Answer 9

24e-

Question 10

What is the result of Reduction?

Answer 10

Glyceraldehyde Phosphate (12 G3P, 3C-1P)

Question 11

What happens in Regeneration?

Answer 11

10 G3P are rearranged. 6ADP+Pi -> 6ATP. This takes it back to RuBP.

Question 12

What happens to 2 G3P?

Answer 12

It is sent to the cytoplasm. The bond is broken, generating the energy to turn it into sugar. This sugar is then used for either starch, cellular respiration, or the cell wall.
