The PSII reaction center leads to easily  inactivation and damage by photoinhibition process while Photosystem I Is Protected from Active Oxygen Species, Why PSI protect from active oxygen species in compare to PSII

#Unit 6. System Physiology – Plant

  1. Because PSI contain ferredoxin acceptor that is a very strong reductant that can easily reduce molecular oxygen to form superoxide (O2 –)

  2. Because PSI contain LHCI Complex that protects the reaction centre from damaging by photoinhibition
  3. Because PSI donot have D1 protein that can easily damage or inactivate by photoinhibition
  4. Because PSI perform a process Nonphotochemical quenching is thought to be involved in protecting the photosynthetic machinery against overexcitation and subsequent damage
