Name one region which lacks PS II?

Open in App

Solution

PSII lacking regions:
Enzymes in the photosystem capture photons of light to excite electrons, which are subsequently transferred to decrease plastoquinone to plastoquinol via a multitude of coenzymes and cofactors.
The energetic electrons are replaced by hydrogen ions and molecular oxygen, which are produced when water is oxidized.
PS II and the NADP reductase enzyme are absent from the stroma lamellae membranes.
