Vedclass · Answer

(D) The light reaction of photosynthesis begins with the absorption of light energy by the pigment molecules (chlorophyll) in the photosystems. When a photon of light strikes the chlorophyll molecule,it transfers its energy to the electrons of the chlorophyll. This causes the electrons to become excited and move to a higher energy state,which is the primary photochemical event that initiates the entire process of photosynthesis.
