When a pigment molecule in a light-harvesting complex absorbs a photon of light, what happens to its excited-state electron?.
MA_775_DIABLO [31]

When a pigment molecule in a light-harvesting complex absorbs a photon of light, While returning to its ground state, the electron transfers some of the energy from its excited state to an electron in a nearby pigment molecule.

  • It takes a photon of light energy some distance before it reaches a pigment molecule like chlorophyll.
  • An electron in the chlorophyll is "activated" by the photon. The energy imparted to the electron then moves from one pigment molecule to another until it reaches the reaction center, a pair of chlorophyll a molecules.
  • An electron in the reaction center is then excited by this energy, causing it to break loose and travel to the primary electron acceptor.
  • Therefore, it is said that the reaction center "donates" one electron to the main electron acceptor.
