What part of PSII appears to suffer most of the damage from high intensity light?
A)the reaction center photopigment
B)the D1 polypeptide of PSII
C)the electrons
D)NADPH
E)both the D1 polypeptide of PSII and NADPH

Question

Quizplus · Accepted Answer

The D1 polypeptide of PSII appears to suffer the most damage from high intensity light. This is because it is directly involved in the process of photooxidation that occurs during photosynthesis. High intensity light can cause the D1 protein to become over-reduced, leading to the formation of harmful reactive oxygen species that can damage the protein and other components of the photosynthetic machinery.
