Photosystem 1 vs 2

Photosystem 2 functions first in the linear electron flow; reaction center chlorophyll a and best absorbs light with 680nm wavelength. 2013-01-23 · Photosystem I (P700) 1) Absorption spectrum peaks at 700 nanometers. 2) Uses FERREDOXIN-LIKE IRON-SULFUR cluster proteins as terminal electron acceptors. Photoexcited electrons travel to photosystem I through an electron transport chain set in the thylakoid membrane. 2006-02-01 · 2.2.

photosystem II One of two light-capturing units in a chloroplast's thylakoid membrane; it has two molecules of P680 chlorophyll a at its reaction center, makes ATP and uses electrons from light NADPH

Sammendrag - Photosystem 1 vs Photosystem 2 De nøkkelforskjell mellom fotosystem 1 og fotosystem 2 er det fotosystemet 1 har et reaksjonssenter som består av klorofyll, et molekyl av P700 som absorberer lys ved en bølgelengde på 700 nm. Photosystem I (PSI) of photosynthesis (Fig. 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.

Huvudskillnaden mellan fotosystem 1 och fotosystem 2 är att fotosystemet 1 har ett reaktionscenter som består av klorofyll en molekyl av P700 som.

· 3. Reaction centre is P700. · 4. 13 Apr 2010 Arrangement of Photosystem II and ATP Synthase in Chloroplast Membranes of The distribution of PSII, LHCI and II, cytochrome b/f, and cF1Fo in plant under any detergent conditions used, ranging from 0.5 to 3% (w/v) 3 Dec 2014 Photosystems, Protein: Photosystem II by femtosecond X-ray pulses, data set 1. Find proteins for P51765 (Thermosynechococcus vulcanus).

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) . 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 . Photosystem II, unlike photosystem I, contains plastoquinone, which passes the energetic electron to cytochromes b6 and f, but photosystem I passes the electron to ferredoxin. In non-cyclic photophosphorylation, photosystem II is associated with the photolysis of water and subsequent synthesis of ATP; photosystem I is associated with the Photosystem II (of cyanobacteria and green plants) is composed of around 20 subunits (depending on the organism) as well as other accessory, light-harvesting proteins.

Photosystem II, unlike photosystem I, contains plastoquinone, which passes the energetic electron to cytochromes b6 and f, but photosystem I passes the electron to ferredoxin. In non-cyclic photophosphorylation, photosystem II is associated with the photolysis of water and subsequent synthesis of ATP; photosystem I is associated with the conversion of NADP+ to NADPH.

However, during the process of photosynthesis, photosystem II comes into play before photosystem I. The main difference between the two is the wavelengths of light to which they respond. Photosystem I absorbs light with wavelengths shorter than 700 nm, whereas photosystem II absorbs light with wavelengths shorter than 680 nm.

How? in the mitochondria, NADH brings electrons and goes down the transport chain it activates proton pumps and creates a gradient. Same goes in photosynthesis.
