11. What is cyclic electron transport? Which photosystem is
used? Is ATP or NADPH created during cyclic electron transport?
What happens to reduced Fd- in cyclic electron transport?

a). The water splitting enzyme is part of which photosystem?
Which side of the thylakoid membrane is it situated? Why? What
metal ions are associated with this enzyme? How many water
molecules are bound initially? What happens each time photosystem
II absorbs a photon? What is the end result of the water splitting
enzyme?

b). An overabundance of reduced PQBH2 can cause what to happen
to the light harvesting complex normally associated with
photosystem II?

c). How many electrons are transferred at each step in the
electron transport chain? How many protons are translocated from
the stroma to the lumen at each step in the chain?
