When PSII receives more light than PSI, plastoquinone becomes predominantly reduced, resulting in activation of the LHCII kinase. The kinase phosphorylates LHCII, resulting in migration of LHCII away from the granal region where it can associate with PSI, thereby adjusting the relative excitation of PSII and PSI.

Buildup of a acidic thylakoid ΔpH in the presence of excess light resulting the thylakoid lumen activates an enzyme (violaxanthin de‐epoxidase) that converts violaxanthin into zeaxanthin
