These centers are a combination of pigments proteins and other co-factors. Non-oxygenic bacteria on the other hand have an RC resembling either the. One is called photosystem I and the other is called photosystem II.
The reaction center is the key component for the primary events in the photochemical conversion of light into chemical energy. Either of two photochemical reaction centers consisting chiefly of photosynthetic pigments complexed with protein and occurring in chloroplasts. The reactions that take place in a photosynthetic reaction center can be summarized by a model reaction sequence in which the components are D an electron donor molecule P the photocatalyst a chlorophyll molecule I an intermediate electron carrier and A an electron acceptor molecule. Photosynthetic reaction centers are membrane-bound pigmentprotein complexes that use light to catalyze a transmembrane electron transfer against a steep thermodynamic gradient. They are transmembrane proteins embedded in the chloroplast thylakoid or bacterial cell membrane. THE CONCEPT AND PHYSICAL REALITY OF REACTION CENTERS RCs The capture of solar radiation and the conversion of its free energy into chemical energy involves a sequence of reactions that occur within a physical structure called the photosynthetic RC.
A reaction centre is laid out in such a way that it captures the energy of a photon using pigment molecules and turns it into a usable form.
Uses it to excite electrons to be transferred to the primary electron acceptor. Either of two photochemical reaction centers consisting chiefly of photosynthetic pigments complexed with protein and occurring in chloroplasts. Plants algae and cyanobacteria have one type of PRC for each of its two photosystems. Photosystem 1 and photosystem 2. One that absorbs light with a wavelength of about 700 nanometers. Type II reaction centers employ a mobile quinone as the terminal electron acceptor.
