No, Photosystems I and II are complexes that take part in the light reactions of photosynthesis, NOT the Calvin cycle.
It is placed as second photosystem in the light reactions of plants, algae and some bacteria. It is an integral membarne protein complex. It functioning the electron transfer from plastocyanin to ferredoxin. Like PSII, PSI also uses light energy to excite electrons.
They come from Photosystem ll. Photosystem ll gets them by ripping the electrons off of water by a process called photolysis. Electrons gain energy first in Photosystem ll, then later in photosystem l, through the absorption of energy from light.
Light dependent reaction occurs in grana (thylakoid stack) of chloroplast. Thylakoid membrane encloses space called lumen. Outside the thylakoid is matrix called stroma. Protein complexes in the thylakoid membrane for absorption of light are Photosystem. Photosystem l (or plastocyanin) absorbs light of wavelength 700nm. Photosystem ll (or water-plastoquinone oxidoreductase) absorbs light of wavelength 680nm. During light reaction, photosystem ll absorbs light and its electron get excited and leave the photosystem ll . It regains the electron from water molecule and splits it into O2 and H+. Plastoquinone gains two H+ (protons) from stroma and two electrons from photosystem ll. It transports protons into the lumen while the electrons move towards the cytochrome b6f protein complex. Cytochrome b6f transfers electron from plastoquinone to plastocyanin. Then photosystem l (P700) accepts electrons from reduced plastocyanin. Ferredoxin is soluble protein complex in photosystem l that carries electron from iron-sulfur complex and transfers it to ferredoxin-NADP+ reductase. Ferredoxin-NADP+ reductase reduses NADP+ to NADPH. H+ which were pumped into lumen through plastoquinone go back into the stroma by passing through ATP synthase. As H+ ions pass through ATP synthase, they cause it to spin. Phosphate group and ADP on it come closer to form ATP. Therefore the products of light reaction are NADPH and ATP molecules.
photosystem l ( for apex! )
No l did not kiss light. Light kissed Misa Amen ..
Light thinks of L as a obstacle and that L has to die. No love included
L and Light do not kiss at all in the show. Sorry!
yesterday l was driving my car at the traffic light, it was in amber light, and l drove through it, but l saw police was standing at the other siade of the traffic light and saw l was driving throught the amber light, l saw he was writing and l thought he was booking my car rego . will l get fine at that moment?
