matching: chose the stage of the light reactions which the statement occurs in.
1. _Produces ATP.
2. _Passes energized electrons down an electron transport chain to create ATP.
3. _Produces NADPH.
4. _Splits water to get electrons to replace energized electrons.
5. _Replaces energized electrons from electrons that have completed the 1st electron transport
chain.
a. water-splitting photosystem.
b. NADPH-Producing photosystem.
Solution
During water splitting photosystem ,the electrons in water are removed and passed to the
chlorophyll. The hydrogen ions extracted from the water molecule, and after two water
molecules are splitted,the oxygen atoms takes electron and form molecular oxygen (O 2 ).
In photosynthesis, water splitting donates electrons to the electron transport chain in
photosystem II.
So it splits water to get electrons to replace energized electrons.
In the photosystem II (PSII) reaction center, energy from sunlight is used to extract electrons
from water. The electrons travel via the chloroplast electron transport chain to photosystem I
(PSI), which reduces NADP+ to NADPH.
So it produces NADPH.
