Photosystem II (PSII), embedded in the thylakoid membranes, catalyzes light-dependent water splitting with concomitant oxygen evolution and electron transfer to the plastoquinone pool. Photosystem II (PSII) is a membrane protein complex which functions to catalyze light-induced water oxidation in oxygenic photosynthesis. On the other hand, the photosystem II has a reaction centre comprising chlorophyll a molecule of P680 that absorbs light at a wavelength of 680 nm. Sie unterscheiden sich in den Wellenlängen der Absorptionsmaxima der Chlorophyllmoleküle ihrer jeweiligen Reaktionszentren. 2.Photosystem II produces ATP while photosystem I produces NADPH. Chlorophyllmoleküle und andere akzessorische Pigmentmoleküle zusammen mit Proteinen und anderen kleinen organischen Verbindungen bilden das Photosystem I und Photosystem II. The diagram does not show where and how ATP is made. 1 decade ago. 4.Photosystem I is sensitive to light wavelengths of 700 nm while photosystem II is sensitive to light wavelengths of 680 nm. Chlorophyll b is more than chlorophyll a. gentle hits PS2, is absorbed by utilising quite a few photosynthetic pigments, and excites the two electrons saved in its base. 3. To be brief, photosynthesis is separated into two parts: the light reactions (photosystem 2 and 1) and the dark reactions (the Calvin cycle). 6. The key difference between photosystem 1 and photosystem 2 is that the photosystem 1 has a reaction centre composing of chlorophyll a molecule of P700 that absorbs light at a wavelength of 700 nm.
