During light reactions phosphate is added to ADP to produce ATP. The process is called Phosphorylation. Dark phase = The Calvin Cycle – is the making of Glucose from CO2. Core Difference Between Photosystem I and Photosystem II. Photosystem I has pigment system 1 while photosystem II has pigment system 2; PS1 is located on the outer surface of the thylakoid membrane while PS2 in the grana of the thylakoid membrane Nedan infographic visar skillnaden mellan fotosystem 1 och fotosystem 2 mer information om dessa skillnader. Sammanfattning - Fotosystem 1 vs Photosystem 2. Fotosystem I och Photosystem II är två huvudsakliga fotosystem som utför ljusberoende reaktioner av fotosyntes i växter. Photosystem I (PSI, or plastocyanin-ferredoxin oxidoreductase) is one of two photosystems in the photosynthetic light reactions of algae, plants, and cyanobacteria.

Treatment of lamellar fragments with neutral detergents releases these particles, designated photosystem I and photosystem II, respectively. Subsequent harsher treatment (with charged detergents Photosystem I or PS I contains chlorophyll A-670, chlorophyll A-680, chlorophyll A-695, chlorophyll A-700, chlorophyll B, and carotenoids in the ratio of 20-30 :1, whereas in Photosystem II or PS 2 contains chlorophyll A-660, chlorophyll A-670, chlorophyll A-680, chlorophyll A-695, chlorophyll A-700, chlorophyll B, xanthophylls and phycobilins in the ratio of 3-7 :1. When photosystem II absorbs light, electrons in the reaction-center chlorophyll are excited to a higher energy level and are trapped by the primary electron acceptors. Photoexcited electrons travel through the cytochrome b6f complex to photosystem I via an electron transport chain set in the thylakoid membrane. Difference # Photosystem II (PS II): 1.

The PSI is made up of two subunits which are psaA and psaB. Regarding your questions #1 ("Is the primary pigment reaction centre in both photosystems a pair of chlorophyll a molecules?") and #3 ("How can it be that it absorbs at a different wavelength in the two photosystems if it is the same molecule?"): Both reaction centers in Photosystem I and Photosystem II contain only chlorophyll a.

Photosystem I is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin. Ultimately, the electrons that are transferred by Photosystem I are used to produce the high energy carrier NADPH. The combined action of the entire photosynthetic electron transport chain also produces a p Start studying photosystem 1 and 2. Learn vocabulary, terms, and more with flashcards, games, and other study tools.

1) provides energy to reduce NADP to NADPH, which is required for carbon fixation and other synthetic processes. Compounds with a redox potential between −300 and −700 mV that can be autooxidized by molecular oxygen can be reduced by PSI, and if stable sufficiently long to diffuse far enough to react with O 2 , they can generate superoxide radicals. Photosystem 2: PS 2 innehåller klorofyll B, klorofyll A-660, klorofyll A-670, klorofyll A-680, klorofyll A-695, klorofyll A-700, phycobiliner och xantofyller. Sammansättning av kärnan Photosystem 1: Kärnan i PS I består av psaA- och psaB-subenheter. of photosystem 2. The maindifference between photosystem 1 and 2 is that PS I absorbs longer wavelengths of light (>680 nm) whereas PS II absorbs shorter wavelengths of light (<680 nm) .
