| 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. |
|
| Each photosystem consists of a light-harvesting complex and a core complex. |
|
| Simazine is a selective systemic herbicide, which acts by inhibiting photosynthetic electron transport at the photosystem II receptor site. |
|
| This arrangement, in which pigment aggregates exist on the thylakoid surfaces, is called a photosystem. |
|
| Treatment of lamellar fragments with neutral detergents releases these particles, designated photosystem I and photosystem II, respectively. |
|
| Photosystem II, the central enzyme in photosynthesis, uses solar energy to remove electrons from water. |
|
| 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. |
