Its turnover rate in chloroplasts can be up to 300 s −1 (reviewed in Hauska et al., 1983; Hope, 1993; Cramer et al., 1994 ).
WebMar 30, 2024 · In PS-1, the reaction centre chlorophyll a, has an absorption peak at 700 nm, hence it is called P700 whereas in PS-2, reaction centre has an absorption peak at 680 nm and it is known as P680. Hence, the correct answer is option (B). Note: Light harvesting complex helps to make photosynthesis more efficient by absorbing different wavelengths … WebPhotosynthesis . PS2. Photosystem II: Harvesting the Photons. It all starts with Photosystem II. Photosystem I comes later; the two complexes are named that way because Photosystem I was discovered before Photosystem II.
