A biochemical mechanism in plants by which chlorophyll absorbs light energy for photosynthesis. There are two such mechanisms (photosystems I and II) involving different chlorophyll–protein complexes.
光合系统
Example sentencesExamples
In photosystem II, a different chlorophyll-protein complex absorbs light at the wavelength of 680 nm.
Thus state transitions appear to act as a mechanism to balance excitation of the two photosystems under changing light regimes.
These trapping kinetics are much slower than observed in photosystem I, the other photosystem of oxygenic photosynthesis.
In higher plant chloroplasts, many pigment-binding proteins are inserted into the thylakoid membrane and organized into multisubunit complexes called photosystems.
Both types of photosystems differ in size, pigment and protein composition, and charge.
