How many types of light-independent reaction cycles are there? What are they?
3: C3; C4; and CAM
What is another name for the C3 cycle?
The Calvin cycle
What is the difference between the light independent reactions?
Different numbers of CO2 molecules in the first step and so, different carbon acceptor molecules.
Where does the Calvin cycle occur?
In the stroma
What happens in the Calvin cycle?
CO2 is converted to glucose.
What does the Calvin cycle require from the light reactions? What are they?
ATP and NADPH; they're energy molecules.
Why make glucose?
It is versatile
What is the first phase of the Calvin cycle called?
Carbon fixation
What happens during the first step of the Calvin cycle?
CO2 is combined with RuBP
What does RuBP stand for?
Ribulose biphosphate
How many carbon atoms and how many phosphate groups does RuBP have?
5 carbon atoms and 2 phosphate groups
What is the enzyme that bonds CO2 and RuBP called?
RuBP carboxylase
What is the shortened name of RuBP carboxylase?
Rubisco
What happens in step 2 of the Calvin cycle?
The unstable C6 molecule formed by CO2 and RuBP immediately splits into 2 PGA molecules.
What does PGA stand for?
phosphoglycerate
How many carbon atoms and how many phosphorous atoms does PGA have?
3 C and 1 P
What happens in step 3?
ATP adds a phosphate group to each of the PGA molecules, converting them to BPG molecules.
What happens in step 4?
NADPH reduces BPG to PGA, and reverts to NADP+
What happens in step 6?
The remaining 10 PGAs combine to form 6 RuBP molecules.
How many ATP molecules are used in total during the regeneration phase of the Calvin cycle per glucose?
6 ATP
What is the total energetic cost of the Calvin cycle per glucose?
18 ATPs and 12 NADPHs --> 1 glucose
What do the stomata control?
They allow CO2 to diffuse in, O2 to diffuse out, and water to evaporate.
