Q
What are the two stages of photosynthesis?
A
The light reactions and the Calvin cycle.
1
Q
Chloroplasts are found mainly in this tissue in a leaf’s interior.
A
mesophyll
2
Q
What are the products of the light reactions?
A
O2, ATP, and NADPH
3
Q
Why does cyclic electron flow exist?
A
It compensates for the higher ATP than NADPH consumption of the Calvin cycle.
4
Q
In chloroplast ATP production, hydrogen ions diffuse through ATP synthase by passing from the ______ to the ______.
A
thylakoid space to the stroma
5
Q
What are the reactants used by the Calvin cycle?
A
ATP, NADPH, and CO2
- To make one molecule of G3P the Calvin cycle consumes:
- 9 ATP
- 6 NADPH
- 3 CO2
6
Q
Where does the Calvin cycle occur?
A
in the stroma
7
Q
What is carbon fixation?
A
The initial incorporation of carbon into organic compounds.
