What does the light-harvesting complex do?
Captures light and funnels energy to the reaction center
What pigment is central to the reaction center?
Chlorophyll a
. What happens to the excited electron in the reaction center?
It is transferred to the primary electron acceptor
How is the lost electron in PSII replaced?
By splitting water (photolysis)
What’s the difference between PSII and PSI reaction centers?
Thylakoid
PSII = P680, PSI = P700
PSI: makes NADP
PSII: makes oxygen
. Does the Calvin Cycle need light?
No, but it depends on ATP/NADPH made by light-dependent reactions
Use chemical energy to fix carbon into sugars
