Difference between psi and psii
WebWhat is PSI and PSII? Introduction. Photosystem I (PSI) and Photosystem II (PSII) harvest light energy to drive photosynthesis. … PSI coordinates several Chls that absorb light at … WebAnswer (1 of 2): Non-cyclic photophosphorylation involves PSII and PSI but cyclic involves only PSI. In non-cyclic, electrons are lost from PSII and are replaced by the electrons from photolysis of water. Non-cyclic also produces reduced NADP and oxygen. In cyclic, excited electrons return to PSI...

WebApr 1, 2015 · An efficient way to screen the balance between PSI and PSII is a comparison of the light responses of the redox poises at PSII acceptor side and PSI donor side, as in well-balanced systems, the symmetric increase of Q − A /Q A and P700 + /P700 (due to “bottleneck effect” of cyt b 6 /f) can be expected (Cardol et al. 2011; Zivcak et al ... WebThe 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. However, they are both equally important in the process of oxygenic photosynthesis. Photosystem I (PSI, or plastocyanin …
