Query: Functional Subsystems and Quantum Redundancy in Photosynthetic Light
  Harvesting   The Fenna-Matthews-Olson (FMO) antennae complex, responsible for light
harvesting in green sulfur bacteria, consists of three monomers, each with
seven chromophores. Here we show that multiple subsystems of the seven
chromophores can transfer energy from either chromophore 1 or 6 to the reaction
center with an efficiency matching or in many cases exceeding that of the full
seven chromophore system. In the FMO complex these functional subsystems
support multiple quantum pathways for efficient energy transfer that provide a
built-in quantum redundancy. There are many instances of redundancy in nature,
providing reliability and protection, and in photosynthetic light harvesting
this quantum redundancy provides protection against the temporary or permanent
loss of one or more chromophores. The complete characterization of functional
subsystems within the FMO complex offers a detailed map of the energy flow
within the FMO complex, which has potential applications to the design of more
efficient photovoltaic devices.
