Compositon of Core Photosystem 1: Inti PS I terdiri daripada subunit psaA dan psaB. 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.

The two main multi-subunit membrane protein complexes differ in their absorbing wavelength, where the photosystem I or PS 1 absorbs the longer wavelength of light which is 700 nm while photosystem II or PS 2 absorbs the shorter wavelength of light 680 nm. 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. 2009-03-12 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.

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. Photosystem I [1] is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin . 2009-03-13 · Historically photosystem I was named "I" since it was discovered before photosystem II, but this does not represent the order of the electron flow. 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.
