1
Q
what is stromas
what 3 things are found in it
A
stroma is the cytoplasm found in the chloroplast and all the orgnelles are found
-Enzymes
-porteins
-starch
2
Q
how many membranes are found on the chloroplasts
A
2
inner- less permiable and uses trasnport proteins
outer- permabole to gases like co2
3
Q
what are starch granual used for in the chlorplasts
A
to store glucose
4
Q
which part of photosynthesis takes place in the stroma
A
light independent reaction
5
Q
what type of DNA is in the chloroplasts
A
circular chloroplast DNA
6
Q
what happens in the kalvin cycle stage 1
A
- co2 enters through the stomata
-combines with 5c Ribulose bipohosphate
enzyme rubisco catytlses the rection and fixated to from a 6c
-6 carbon molecule immediatly brakes up to form 2 3 carbon molecules of glyceratphosphate
7
Q
what happens in the kalvin cycle stage 2
A
- with the energy from the light dependent reaction and H+ from reduced NADP reduces GP
-forms 2 3 molecules of trisphotsphate
-ADP and NADP molecules return to thaylakoid
-
8
Q
what happens in stage 3 of the Calvin cycle
A
-5c of the triosphosphate is needed to regenegrate the cycle but 1 is realseased for organic molecules
-atp is used to
