Hint
Answer
% Correct
In CO2 fixation in the stroma of the thylakoid, the CO2 is first fixed to _
_
_
_
_
_
_
_
_
ribulose 1,5 bisphosphate
100%
Rubisco is a slow enzyme capable of putting 3 _
_
_
_
molecules on ribulose 1,5 bisphosphate per second
CO2
100%
_
_
_
_
_
_
is the most abundant protein on earth
Rubisco
100%
First stage of calvin cycle is the _
_
_
_
_
_
_
_
of ribulose 1,5 bisphosphate and splitting the product into two molecules of 3-
phosphoglycerate
carboxylation
100%
Second stage of calvin cycle is the reduction of _
_
_
_
_
to form glyceraldehyde-
3-
phosphate using ATP and NADPH
3-phosphoglycerate
100%
The calvin cycle occurs in the _
_
_
_
of the chlorplast
stroma
100%
The enzyyme for adding CO2 to ribulose 1, bisphosphate and splitting it into two molecules of 3-
phosphoglycerate is
ribulose bisphosphate carboxylase
0%
Third stage is the regeneration of the _
_
_
_
_
_
_
_
using ATP as energy
ribulose 1,5 bisphosphate
0%
The actual change of glyceraldehyde-
3-
phosphate to sucrose occurs in the _
_
_
_
cytoplasm
0%
For every _
_
_
CO2 molecues fixed, 12 _
_
_
_
_
are produced
6, glyceraldehyde-3-phosphate
0%
Then the 12 molecules of glyceraldehyde-
3-
phosphate are used to regenerate _
_
_
_
_
_
_
_
and two molecules of glyceraldehyde-
3-
phosphate will be exported to the _
_
_
_
_
to make sucrose
ribulose 1,5 bisphosphate, cytoplasm
0%
The glyceraldehyde-
3-
phosphate can also stay in the chloroplast and make _
_
_
_
starch
0%
The 12 3-
phosphoglycerate uses _
_
_
_
ATP to turn itself into _
_
_
1,3-
bisphosphoglycerate
12,12
0%
The 12 _
_
_
_
_
_
_
_
_
_
_
_
uses 12 NADPH to create 12 glyceraldehyde-
3-
phosphate
1,3 bisphosphoglycerate
0%
Hint
Answer
% Correct
The glyceraldehyde3-
phosphate turns into the _
_
_
_
with 6 ATP
ribulose 1,5 bisphosphate
0%
Plants that first incorporate CO2 into a 4-
carbon compound are called _
_
_
_
plants and they live in dry, arid regions
C4
0%
C4 plants have adapted to low _
_
_
_
levels that allows for maximum photosynthesis with low CO2 (created by closing of the stomata
CO2
0%
For C4, CO2 enters calvin cycle and is fixed to _
_
_
_
_
_
phosphoenol pyruvate
0%
For C4 plants,CO2 + PEP is equal to _
_
_
_
_
oxaloacetate
0%
Oxaloacetate uses one NADPH to become _
_
_
_
_
malate
0%
Malate creates one NADPH to pass of CO2 to ribulose bisphosphate carboxylase and _
_
_
_
_
pyruvate
0%
Pyruvate uses one _
_
_
_
to become _
_
_
_
ATP, PEP
0%
The _
_
_
_
_
_
_
_
is the 4-
carbon molecule of the C4 plants
oxaloacetate
0%
The Calvin Cycle happens in the _
_
_
_
stroma
0%
The change of glyeraldehyde-
3-
phosphate to starch occurs in the _
_
_
_
stroma
0%
The change of glyceraldehyde-
3-
phosphate to sucrose occurs in the _
_
_
_
_
_
_
cytoplasm
0%
The _
_
_
_
_
_
is used as an energy source for plants in the dark hours
starch
