2 H2O + 2 plastoquinone + 4 hv illumination of spinach PSII membranes deprived of intrinsic plastoquinone results in 1O2 formation, singlet oxygen scavenging activity of plastoquinol in photosystem II, significantly suppressed by addition of exogenous plastoquinol to plastoquinone-depleted PSII membranes. Presence of exogenous plastoquinols with a different side-chain length causes a similar extent of 1O2 scavenging activity Spinacia oleracea O2 + 2 plastoquinol
