Question

A SPAD meter detects these molecules. A dimer of these molecules is the “special pair” that gets oxidized to kick off both cyclic and non-cyclic electron flow. The concentration of these molecules is maximized about 100 meters deep in the ocean at the layer where primary productivity is greatest. Phycobilins fill in the gaps between these molecules’ 460 (20[1])and (20[1])660-nanometer (20[1])absorbance peaks in (*) antenna complexes in cyanobacteria. The a type of this molecule is a reduced (10[1])porphyrin (10[1])that (10[1])coordinates magnesium. In the LDRs, these molecules donate the electrons that flow to NADPH and provide energy to pump protons across the thylakoid membrane. For 10 points, name these green pigments used by plants for (10[1])photosynthesis. ■END■ (10[3])
