Flashcards in Photosynthesis: Light Independent reactions Deck (7):
1

Where do light independent reactions occur

Occurs in the stroma of the chloroplasts

2

What are the 3 stages of Calvin cycle

1. Carbon fixation

2. Reduction reactions

3. RuBp regeneration

3

What happens in the carbon fixation stage (steps and products)

1. 3 molecules of CO2 convert 3 molecules of 5 carbon RuBp into 3 6 carbon molecules

2. 3 6 carbon molecules break down with water and from 6 molecules of 3-PGA

4

What happens in reduction reactions ( steps and products)

1. 6 3-PGA phosphorylated by 6 ATP to make 6 molecules of 1,3-PGA

2. 6 molecules of 1,3-PGA are reduced by 6 NADPH to make 6 molecules of 63P

5

What happens in RuBp regeneration

5 molecules G3P phosphorylated by 3 ATP and 2 H2O to make three RuBp

6

How many times does the Calvin cycle occur to make a glucose molecule

6 cycles

7

What is the structure of G3P

3 carbon molecule
