Contains pigments, photosystems, ATP synthase, and an electron transport train and is responsible for the light-dependent aspect of photosynthesis.


(Energy conversion phase: Formation of ATP and NADPH). The major difference between photosystems 1 and 2 is that photosystem 1 lies on the outer surface of  

Das Reaktionszentrum des Photosystems I hat ein Absorptionsmaximum bei einer Wellenlänge von 700 nm, es wird deshalb auch als „P700“ bezeichnet. Das Photosystem II enthält insgesamt zirka 250 Moleküle Chlorophyll a und b sowie ca. 110 Carotinoide. Photosystem 1 vs Photosystem 2 .

When it grabs electrons from a water molecule, photosystem II splits the water and releases oxygen gas. This reaction is the source of all of the oxygen that we breathe. 2020-03-11 Photosystem I Complex.

Photosystem I is very receptive to light waves at the 700 nm wavelength. In comparison, photosystem II is very receptive to light wavelengths of around 680 nm. Both photosystem I and II are necessary in most plants to produce the energy they need from the sun. Although both do the same thing, it is the way they do it that sets apart their differences. Still, the ATP and NADPH they produce are used by the plant as energy sources for its biological processes.

Each core complex contains a reaction centre with the pigment (either P 700 or P 680) that can be photochemically oxidized, together with electron acceptors and electron donors. In addition, the core complex has some 40 to 60 chlorophyll molecules bound to proteins.

Photosystem 1

Photosystem II (PS II) donates electrons to photosystem I where NADP+ is reduced. 3. This system is responsible for the photolysis of water and involves the evolution of molecular oxygen. 4. Photosystem I (PS-I) and photosystem II (PS-II) are two multi-subunit complexes that laid inside the thylakoid membrane of chloroplast and involved in the process of photosynthesis.
