5.6 Photosynthesis Flashcards
1
Q
What is Photolysis
A
Splitting up water molecules using light energy.
2
Q
Where in photosynthesis does photolysis occur.
A
Photosystem 2 in the light dependent stage.
3
Q
What is Photophosphorylation
A
Using light to add an inorganic phosphate ion to ADP to make ATP.
4
Q
What enzyme catalyses photophosphorylation?
A
ATP Synthase
5
Q
What is NADP
A
A coenzyme that transfers a hydrogen atom from one molecule to another (reducing and oxidising).
6
Q
What is reduced NADP shown as?
A
NAPDH
7
Q
What are the 3 uses of light energy in the light dependent stage of photosynthesis?
A
- photolysis
- reducing NAPD to NAPDH
- photophosphorylation
8
Q
When is NAPD reduced
A
Photosystem 1 in the light dependent stage.
9
Q
What are the 2 types of photophosphorylation
A
Cyclic and Non cyclic
10
Q
What is the function of the electron transport chain
A
To carry electrons form PS2 to PS1
