Light-Dependent Reaction Flashcards
1
Q
What is the first stage of LDR?
A
light energy is absorbed by PSII
excited electrons - higher energy level
electrons move along ETC
2
Q
What is the second stage of LDR?
A
Photolysis of water produces H+, electrons and O2
Electrons are replaced in PSII from this
3
Q
Why do the electrons need to be replaced in LDR?
A
Electrons leave PSII and conc gradient decreases so they need to be replaced
4
Q
Where does the LDR take place?
A
Thylakoid membranes
