light independent

Question 1

what does the stage require and not require

Answer 1

the stage doesn’t require light however the roducts of light dependent is needed

Question 2

what happens to the co2

Answer 2

it diffuses through the stomata and dissolves in the water arounf the mesophyll cells, it then diffuses through the cell membrane , cytoplasm and chloroplast into the stroma

Question 3

what happens in the stroma with the co2

Answer 3

the co2 reacts with the 5 carbon ribulose biophospate catalysed by ribusco

Question 4

what the reaction between co2 and rubp produce

Answer 4

two molecules of the 3 carbon molecule GP

Question 5

what happens to the gp and using what

Answer 5

the gp is reduced to triose phosphate using nadph and the energy provided from atp

Question 6

What happens to nadp

Answer 6

it is reformed and goes back to the light dependent reaction to be reduced again by accepting more protons

Question 7

What are the tp converted into

Answer 7

they are converted into organic substances like glucose and starch and some are usrd to regenerate RUBP by using ATP
