Photosynthesis Flashcards
1
Q
Site of the light-dependent reaction
A
Thylakoids of the chloroplast
2
Q
Site of the light-independent reaction
A
Stroma of the chloroplast
3
Q
What happens when the chlorophyll absorbs light energy?
A
Boosts the energy of electrons
These become excited and leave the chlorophyll and are taken up by an electron carrier
4
Q
What happens to the lost energy from each stage of the transfer chain?
A
Used to combine Pi and ADP to make ATP
5
Q
What is photolysis?
A
The replacement of electrons in the chlorophyll
Provided by splitting water molecules using light energy
The hydrogen released is used to reduce NADP
6
Q
Why are ATP and NADPH required for the light independent reaction?
A
To reduce the activated GP to TP
NADP can then be re used in the light dependent reaction again
