Synergic enhancement between different kinds of these complexes 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. DMCU inhibits the activity of one of these complexes by blocking the binding site of plasto·quinone (“plass-toe-KWIE-known”) B. One of these complexes pulls four electrons from two (*) water molecules using a manganese-containing OEC (“O-E-C”) enzyme. 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 of photosynthesis? ■END■
