Question 1: Make a flow chart of the light-dependent process that begins with a photon of light energy coming in contact with a chlorophyll molecule in photosystem II and ends with the loss of an electron to plastoquinone (Pq) carrier protein.

Question 2: Electrons lost by the P680 molecule are replaced how?

Question 3: Plants give off molecular oxygen (O2(g)) that we breathe as a product of the light-dependent reaction of photosynthesis. Describe, the process within photosystem II whereby water molecules absorbed by plants are converted to molecular oxygen.

Question 4: Which other action is coupled with the transfer of an electron from plastoquinone to the cytochrome complex? What type of electrochemical situation is this creating across the thylakoid membrane?

Question 5: As electrons move from photosystem II to photosystem I, they lose energy. How are electrons re-energized in photosystem I? What is the role of these two re-energized electrons ultimately?

Question 6: Briefly describe how ATP synthase obtains energy in order to power the phosphorylation of ADP to ATP?
