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. Photosystem II (PS II) is involved only in non-cyclic photophosphorylation. 2.

2016-09-16 Accordingly chlorophylls exist two photosystems, namely photosystem I (PS I) and photosystem II (PS II). Both photosystem ( PS I and PS II ) are affected by light with wavelengths shorter than 680nm (nanometer), while photosystem I is affected by light with wavelengths longer than 680nm. The primary function of the photosystem I is in NADPH synthesis, where it receives the electrons from PS II. The primary function of the photosystem II is in the hydrolysis of water and ATP synthesis. The PSI is made up of two subunits which are psaA and psaB.

Structural biology studies of thylakoid lumen proteins required

1996-09-29 · Photosystem II, photosystem I, and the components of the photosynthetic electron transport chain are intrinsic proteins of the thylakoid membranes of the chloroplast. A schematic diagram of the important enzymes of the thylakoid membranes, showing the path of electrons and protons during the light reactions is shown to the right. Under certain conditions, the photoexcited electrons take an alternative path called cyclic electron flow, which uses photosystem I (P700) but not photosystem II (P680). This process produces no NADPH and no O 2, but it does make ATP. This is called cyclic photophosphorylation. In addition to the major photosynthetic complexes photosystem II (PSII), cytochrome b6f, and photosystem I (PSI), chloroplasts also contain minor components, including a well-conserved type I NADH dehydrogenase (NDH-1) complex that functions in close relationship with photosynthesis and likewise originated from the endosymbiotic cyanobacterial ancestor. Hauptunterschied - Photosystem 1 vs.

This means that the ATP synthase covers ∼20% of the unstacked thylakoid surface, with an average center-to-center distance of 27 nm, or 15 nm edge-to-edge.
