Photosystem II is named as such since it is discovered after photosystem I. Their names do not represent the electron flow as it begins in photosystem II I (i.e. when both of them are present in the organism, e.g plants and algae).
Qualitative modelling and analysis of Photosystem II
Photosystem I is arranged 2 . or stroma. lipid droplets and starch grains. called grana.Photosynthesis Compiled by сᴏᴏʟιᴏ Q 1 Describe how. The pigment molecules are also arranged in particular light-harvesting clusters for efficient light absorption. in the form of ATP. The pigments are arranged in light harvesting clusters called photosystems. [June 2013 # 1] The pigments are méthode de recherche d emploi pdf between these two states are called the state 1 and state 2 transitions.The two states, 1 and 2, are acclimatory states in which total absorbed excitation energy tends to become distributed equally between the two photosystems (Myers 1971). The Z-scheme or two-light reaction model requires that the rates of electron transport at the two reaction centres are equal (Hill & Bendall 1960). However

Abstract. It is widely believed that the photosystem II (PSII) complex may function as a dimer in the thylakoid membrane. Here, we report experimental conversion from the monomeric PSII to the dimeric form by treatment with high concentrations of n-dodecyl-β-d-maltopyranoside (DM). linux command line cheat sheet pdf 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. Photosystem I includes the following pigments: Chlorophyll b, Chlorophyll -a 670, Chlorophyll -a 680, Chlorophyll -a 695, Chlorophyll -a 700 or P700, Carotenoids.

The interaction of phospho-LHC II with Photosystem 1 (PS 1) was studied for two types of PS I preparation. Changes in the chlorophyll a/b ratio and the ratio of 650 and 680 nm band intensities (E650/E680) in fluorescence excitation spectra were used in calculating the phospho-LHC II portion which became associated with PS 1.
- A second photochemical turnover reduces Q B − to Q B 2−, which is then protonated to plastoquinol PQH 2 and released from the Q B-binding site of PSII into the lipid bilayer, where it is subsequently oxidized by photosystem I (PSI) via the cytochrome b 6 f complex.
- Two forms of the signal were investigated: 1), the native g ~ 1.9 form; and 2), the g ~ 1.84 form, which is well known in purple bacterial reaction centers and occurs in photosystem II when treated with formate.

- the reducing agent produced from the light reaction of photosystem 1. During photosynthesis CO 2 and H 2 O are absorbed to form carbohy-drates, proteins and fats. The generalised symbol CH 2 O is used to indicate the basic building block for these products. CO 2 is released during respi-ration of both plants and animals, and by the combustion of biological material. This simplified explanation
