Question

Explain how light energy is funneled from the antenna to the special pair resulting in electric charge separation at the reaction centre chlorophyll.

Answer 1

A photon strikes the antenna pigments of photosystem II to initiate photosynthesis. The energy travels to the reaction center that contains chlorophyll a to the electron transport chain, which pumps hydrogen ions into the thylakoid interior. This action builds up a high concentration of ions.
