The right answer is C - 'Excited' Electron
In the clear phase of photosynthesis, when a chlorophyll picks up a photon corresponding to its absorption capacity, one of its electrons goes into a so-called excited state. This energy can be transmitted in three ways: either by spreading it in the form of a photon, or by spreading it in the form of heat (both ways of losing energy), or by transmitting the energy by resonance with almost no loss. energy.
