what will be the result of photosystem II being exposed to less sunlight more glucose molecules will be produced
melisa1 [442]

Fewer hydrogen ions will be pumped into the Thylakoid when photosystem II being exposed to less sunlight more glucose molecules will be produced.

Photosystem II is the first membrane protein complex in oxygenic photosynthetic organisms in nature. It produces atmospheric oxygen to catalyze the photo-oxidation of water by using light energy. It oxidizes two molecules of water into one molecule of molecular oxygen.

Photosystem II the energy derived from absorption of photons is used to split water molecules to molecular oxygen and protons. The most important function of photosystem II (PSII) is its action as a water-plastoquinone oxido-reductase. At the expense of light energy, water is split, and oxygen and plastoquinol are formed.
