The first reaction that converts electron energy into chemical energy—What will happened in  the primary photochemical event—

#SCPH05 I Biotechnology
  1. The transfer of an electron from the excited state of a chlorophyll in the reaction centre to an acceptor molecule-pheophytin
  2. The reaction centre chlorophyll is in an oxidized state (electron deficient, or positively charged), and the nearby electron acceptor molecule is reduced (electron rich, or negatively charged)
  3. The reaction centre chlorophyll is in an oxidized state (electron deficient, or negatively charged), and the nearby electron acceptor molecule is reduced (positively charged)
  4. The transfer of an electron from the excited state of a chlorophyll in the reaction centre to an acceptor molecule- plastocyanin
