Difference in sensitivity to photoinhibition between photosystem II in the appressed and non‐appressed thylakoid regions

Thylakoid vesicles containing photosystem II from either the appressed or non‐appressed thylakoid region were subjected to photoinhibitory illumination. Photosystem II from the non‐appressed region was found to be less sensitive to photoinhibition compared to photosystem II from the oppressed region under both aerobic and anaerobic conditions.
