Protection against photodamage is a multilevel process, excited state of chlorophyll is not rapidly quenched by photochemistry it can react with molecular oxygen to form toxic photoproducts such as as singlet oxygen (1 O2*) what can damage if this second line of defense also fails to eliminate the reactive photoproducts?

#Unit 6. System Physiology – Plant
  1. the photoproducts can damage the LHC I protein of PSI, this damage leads to photoinhibition
  2. the photoproducts can damage the D2 protein of PSI, this damage leads to photoinhibition
  3. the photoproducts can damage the LHC II protein of PSII, this damage leads to photoinhibition

  4. the photoproducts can damage the D1 protein of PSII, this damage leads to photoinhibition
