| Treatment of lamellar fragments with neutral detergents releases these particles, designated photosystem I and photosystem II, respectively. |
| To convert sunlight into a usable form of energy, photosynthetic organisms require water at the active site of the Photosystem II protein complex. |
| The result of this damage is up to a 20 percent reduction in the productivity in Photosystem II over the course of a few hours of photosynthetic activity during daylight hours for plants. |
| Simazine is a selective systemic herbicide, which acts by inhibiting photosynthetic electron transport at the photosystem II receptor site. |
| In photosystem II, a different chlorophyll-protein complex absorbs light at the wavelength of 680 nm. |
| These trapping kinetics are much slower than observed in photosystem I, the other photosystem of oxygenic photosynthesis. |
