Visible Light It may look white but its comprised of all the colors we see. Each color has a characteristic wavelength. To see individual colors, so-called white light (visible light) must be bent through a prism.

This figure shows an overlay of the absorption spectrum of chlorophyll A (in green) and action spectrum (in black) for photosynthesis. Why are they different? a) Green/yellow light block the absorption of red/blue light b) Probably the result of inaccurate measurements c) Other pigments absorb light in addition to chlorophyll A

Unformatted text preview: 500nm and 600-700nm? Why are they not in the GREEN area? Excitation of chlorophyll Transition from ground state to excited state Excited state has more energy based on its position When it falls, it releases energy Question: Is the fall of an electron endergonic or exergonic? How do photosynthetic organisms use this process to power needed anabolic processes? Questions: Is the fall of an electron endergonic or exergonic? Is an electron “falling” here? How do photosynthetic organisms use this process to power needed anabolic processes? How is this image different from Fig 10.11a? Where is the pH highest? Intermembrane space or matrix (MITOCHONDRIUM) stroma or thylakoid space (CHLOROPLAST) Calvin Cycle Carbon fixation 3 CO2 combines with Ribulose Biphosphate to make a 6 carbon molecule Reduction NADPH reduces the carbon molecule to glyceraldehyde-3-phosphate Regeneration of RuBP...
