Vedclass · Answer

(B) The first step in the light-dependent reactions of photosynthesis is the absorption of light energy by chlorophyll molecules.When a photon of light energy strikes a chlorophyll molecule,it causes the excitation of an electron from its ground state to a higher energy level (excited singlet state).This photoexcitation leads to the ejection of an electron from the chlorophyll molecule,which then initiates the electron transport chain.Therefore,the correct sequence begins with the photoexcitation of chlorophyll.
