Question

Synergic enhancement between these complexes in certain conditions can be explained by the Emerson effect. LHCII (“L-H-C-2”) is laterally migrated between two states during a shift in energy balance between these complexes. Changes in redox potential within these complexes can be visualized using Z-scheme diagrams. (15[1])DMCU (15[1])inhibits the activity of one of these complexes by blocking the binding site of (*) plasto·quinone (“plass-toe-KWIE-noen”) B. One of these complexes pulls four electrons from two water molecules using a manganese-containing OEC (“O-E-C”) enzyme. (10[1])These protein complexes, which use pigment-rich antenna complexes to absorb photons, are embedded in the thylakoid (“THIGH-luh-koyd”) membrane. Light energy is converted into chemical energy in plants by, for 10 points, what functional units (10[1])of photosynthesis? ■END■

ANSWER: photosystems [or PSs; accept photosystem I or PSI; accept photosystem II or PSII; prompt on oxygen-evolving complexes or OECs until “OEC” is read]
