Question

OEC OEC OEC OEC Thylakoid lumen FKBP20-2 P18.3 Phosphorylation by STN7 and STN8 kinases PSII inactivation DI protein damage Assembly of OEC Assembly of PSII-LHCI Grana thylakoids Grana margins, stroma thylakoids Dephosphorylation by PBCP Di proteolysis LPA19 PSB27 TLP18.3 PPLI Targeting of DI nascent chain to cpSecY translocon by cpSRP54 Co-translational insertion of DI protein Ligation of cofactors C-terminal processingot D1 by CtpA Protection of PSII donor side Reassembly of CP43 pshA mRNA cpSRP54 AtPDI6 LPAI ICF24 2 ICF136 CYP38

Explanation / Answer

In image 1, it is the repair cycle of Photosystem-II which basically repairs the damaged D1 protein for the proper functioning of PS-II.

In image 2, the regulation of PS-II is shown, how the pumping of protons from thylakoid lumen to stroma lead to formation of proton motive force , which is used by ATP synthase in production of ATP
