The photon intensity captured by green plants is used in the following processes:
(i) Photosynthesis
(ii) Generation of heat
(iii) Production of toxic products such as superoxide, singlet oxygen etc.
(iv) Damage to D1 protein of PSII
Based on the above facts, photoinhibiton will happen when the:
1
entire photon intensity is used for photosynthesis
2
excess photon intensity is completely used for heat generation
3
excess photon intensity is used for heat generation and formation of toxic products
4
excess photon intensity leads to the damage of D1 protein
5
