Lecture 5: 1) Draw the Z-Scheme with the following components: Water, O2, Mn Center, P680, plastocyanin, Pheophytin, Plastoquinone, Cytb6f, P700, Chl, Phyloquinone, Fe-S centers, NADP, NADPH, and Ferredoxin (THESE ARE NOT IN ANY PARTICULAR ORDER) 2) Photosystem I is the site of oxygen evolution? True/False 3) Non-cyclic e- transport generates a(n). .. 4) Explain why light with a wavelength > 680 fails to evolve oxygen 5) Why does adding a background of green light combined with higher wavelength light (> 680nm) result in oxygen evolution? 6) Green light can only reduce the components between PSII and PSI? True/False 7) Far Red light can only oxidize the components between PSII and PSI? True/False

Unformatted text preview: 8) How does far-red light decrease the fluorescence from PSII? 9) PSII and PSI are concentrated in different regions of the thylakoid membrane. Where are the majority of the PSII located and the majority of PSI? 10) How does LHCII move between the two photosystems to regulate their efficacy? 11) What ratio appears to regulate the kinase that phosphorylates LHCII? 12) How many photons are required to evolve oxygen initially? Following the first oxygen, how many photons are required to evolve the second molecule of oxygen? Explain the difference. 13) The "Q cycle" enables the cytb6f complex to pump 4 protons for each QH2 into the stromal space. True/False...
