WebFigure 8.16 A photosystem consists of 1) a light-harvesting complex and 2) a reaction center. Pigments in the light-harvesting complex pass light energy to two special chlorophyll a molecules in the reaction center. The light excites an electron from the chlorophyll a pair, which passes to the primary electron acceptor. An FM radio station transmitting at 100 MHz emits photons with an energy of about 4.1357 × 10 eV. This minuscule amount of energy is approximately 8 × 10 times the electron's mass (via mass-energy equivalence). Very-high-energy gamma rays have photon energies of 100 GeV to over 1 PeV (10 to 10 electronvolts) or 16 nanojoules to 160 microjoules. This corresponds to frequencies of 2.42 × 1… st maurice winnipeg
