Question

Quizplus · Accepted Answer

When PSII is overexcited by high intensity light, it can transfer excess energy to oxygen molecules, leading to the formation of toxic oxygen species such as singlet oxygen and superoxide radicals. These reactive oxygen species can damage PSII and other cellular components through oxidative stress.
