Lecture 19( light reactions)

Where are chloroplasts located

located inside of photosystems within the thylakoid membrane

Light reactions occur in..

thylakoid membrane

Antenna chlorohphyl are used to..

used to absorb and emit photon energy to the reaction center

Energy released from the reaction center go to..

electron transport chain

Electrons from the chlorophyll reaction center are replaced by..

electron donor

Where does photosystem 2 gets electrons from

water

where does photosystem 1 get its electrons from

photosystem 2

ATP is made through the build up of

proton gradient that moves through a channel ion to drive ATP, extra electron from photosytem 1 get used

How is NADPH made?

re-energized electrons from light energy of photosystem 1 reduce NADP+

Antenna chlorophylls are present in..

both PS1 and PS2
