In PS I, the reaction centre Chl a has absorption peak at ____whereas in PS II, the reaction centre Chl a has absorption maxima at ______

View answer and explanation

Correct option: A

700 nm, 680nm

Option A (700 nm, 680nm) is correct because the reaction center chlorophyll a in PSI (P700) has an absorption peak at 700 nm, while the reaction center chlorophyll a in PSII (P680) has an absorption peak at 680 nm.
