Final: Photosynthesis Flashcards
1
Q
What are the stages of ps?
A
- Light dependant reactions
- light independant reactions (calvin cycle)
2
Q
Where do they take place?
A
- across the thylakoid mem
- stroma
3
Q
where is the higher pH?
stroma or thylakoid?
A
Stroma!
4
Q
How are the pigments in chloroplasts able to capture energy from the sun?
A
The pigment molecules have antenias that catch the energy
5
Q
What is RuBisCo?
A
enzyme that takes Co2 from the atmosphere and combines it with RuBP and fixes it in the cell
6
Q
What is RuBP?
A
made in the calvin cycle
7
Q
What are the inputs and outputs of the light independant reactions (CC)
A
Ins: Co2, NADPH, ATP
Outs: GA3P
8
Q
What are the inputs and outputs of the light dependent reactions?
A
Ins: H2O, light
Outs: ATP, O2, NADPH
9
Q
What is the point of PS?
A
to take energy from the sun to harvest light energy specifically making sugars
