Redigerer Fotoinhibering

'''Fotoinhibering''' er en lysindusert reduksjon i fotosyntesekapasiteten i [[planter]], [[alger]] eller [[blågrønnbakterier]]. [[Fotosystem II]] (PSII) er mer sensitivt overfor lys enn resten av fotosynteseapparatet, og forskere brukere derfor ofte begrepet fotoinhibering om lysinduserte skader på fotosystem II. I levende organismer ([[in vivo]] forsøk), blir de skadde reaksjonssenterne i fotosystem II kontinuerlig repareret. Dette skjer ved at D1-proteinet i reaksjonssenteret brytes ned og nytt D1-protein syntetiseres. Det er tilgjengelig en rekke reviewartikler som omhandler fotoinhibering.
