Question

A protein serving as a transfer agent into one of these complexes was the first “blue copper” protein to have its antiparallel beta barrel structure characterized. Proteins like R-PE and B-PE create rods of stacked cylindrical subunits (10[1])in one of these complexes called (10[1]-5[1])phycobilisomes. (10[1])A subunit of one of these complexes goes through five states (10[1])labeled S-sub-0 (10[1])to S-sub-4 (10[1])in a cycle named for (10[2])Bessel Kok. Three clusters in one of these complexes labelled Fx, Fa, and Fb facilitate (10[1])electron transfer to (10[1])ferredoxin. (10[1]-5[1])Cytochrome (10[1]-5[1])b6f, plastoquinone, and (10[1])plastocyanin (10[2])shuttle (-5[2])electrons (-5[1])between two of these (10[1]-5[1])complexes, (10[4])one of which contains (10[1])the oxygen-evolving complex. (-5[1])For 10 points, name these protein complexes inside thylakoid membranes (10[2])involved (10[1])in the light-dependent reactions (10[1]-5[1])of photosynthesis, (10[1]-5[2])which are labeled I and II. (10[1])■END■ (10[8]0[8])

ANSWER: photosystems [accept photosystem I or photosystem II or PS I or PS II; accept P680 or P700; accept plastocyanin-ferredoxin oxidoreductase or water-plastoquinone oxidoreductase; prompt on thylakoids or thylakoid membranes until read; prompt on chloroplasts; prompt on oxygen-evolving complex until read by asking “what structure is that located within?”]
