Primary acceptor of ps2
WebThe stoichiometry of the primary acceptor of PS2 (Q) and the PSI reaction centre chlorophyll (P700) was determined in 5 different thylakoid fractions. The starting Yeda press homogenate (YPH) was separated by centrifugation into a grana stack fraction (Y-40) and a stroma lamellae vesicle fraction (Y-100). WebPheophytin. Pheophytin serves as the first electron carrier intermediate in the electron transfer pathway of Photosystem II (PS II) in plants, and the photosynthetic reaction …

Following excitation, the loosened electron of P680* is taken up by the primary electron acceptor, a pheophytin molecule located within photosystem II near P680. During this transfer, ... WebJul 7, 2024 · Photosystem II obtains replacement electrons from water molecules, resulting in their split into hydrogen ions (H+) and oxygen atoms. The oxygen atoms combine to form molecular oxygen (O 2 ), which is released into the atmosphere. The hydrogen ions are released into the lumen.
