Action of 2,6-Dichloro-1,4-benzoquinone on the O-Evolving Activity of Photosystem II in Cells with and without Cell Wall: Inhibitory Effect of Its Oxidized Form.

is a widely used object in studies on green algae concerning both photosynthesis aspects and possible biotechnological approaches. The measurement of the maximum O evolution by photosystem II (PSII) in living algal cells in the presence of artificial acceptors is one of the commonly used methods for determining the photosynthetic apparatus state or its change as compared to a control, parent strain, etc., because PSII is the most sensitive component of the thylakoid membrane.
